For f(x), the transformation of the function is stated in the first column. Determine the type of transformation
The first column of the transformation of the function contains information on the transformation of the functions f(x) - f(x) -2.
What is functions ?The study of mathematics comprises the study of quantities and their variations, equations and associated structures, shapes and their positions, and locations where they can be found. A combination of inputs and corresponding outputs are referred to as a "function," which describes the relationship between them. The term "function" refers to an association between inputs and outputs where each input produces a single, unique result. There are two domains, or scopes, assigned to each function. Usually, the symbol f is used to signify functions (x). input is an x. There are four basic categories of functions that are available: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

what is the inverse f(x)=3x^3-4
Answer:
f^-1(x) = [tex]\sqrt[3]{(x + 4)/3}[/tex]
Step-by-step explanation:
y = 3x^3 - 4 ==> solve for x
y + 4 = 3x^3 ==> isolate x by adding 4 on both sides
(y + 4)/3 = x^3 ==> divide 3 into both sides
x = [tex]\sqrt[3]{(y + 4)/3}[/tex] ==> isolate x by taking the cube root on both sides
y = [tex]\sqrt[3]{(x + 4)/3}[/tex] ==> switch both x and y

If a fair coin is tossed 9 times, what is the probability, rounded to the nearest
thousandth,
of getting at most 1 heads?
When a fair coin is tossed nine times, there is a 0.090 (rounded off to the nearest thousandth) chance that at most one will land on heads.
what is probability ?The probability that an event will occur or a claim will be true is measured by probability theory, a branch of mathematics. The probability of an occurrence is a number between 0 and 1, where about 0 represents how likely the event is to occur and 1 represents certainty. A probability is a numerical illustration of the possibility that a specific occurrence will take place. Probabilities can also be expressed as percentages ranging from 0% to 100% or from 0 to 1. the ratio of the total number of outcomes to the proportion of occurrences in a whole set of equally likely options that lead to a specific occurrence.

Step-by-step explanation:
the magnitude of a vector < a, b, c > is

given vector < 1, 2, x > has magnitude of 3 , then
[tex]\sqrt{1^2+2^2+x^2}[/tex] = 3

What are the solutions of x² - 5x+7=0?
Answer:
x = 5/2 + (i sqrt(3))/2 or x = 5/2 - (i sqrt(3))/2
Step-by-step explanation:
Solve for x:
x^2 - 5 x + 7 = 0
Subtract 7 from both sides:
x^2 - 5 x = -7
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = -3/4
Write the left hand side as a square:
(x - 5/2)^2 = -3/4
Take the square root of both sides:
x - 5/2 = (i sqrt(3))/2 or x - 5/2 = -(i sqrt(3))/2
Add 5/2 to both sides:
x = 5/2 + (i sqrt(3))/2 or x - 5/2 = -(i sqrt(3))/2
Add 5/2 to both sides:
Answer: x = 5/2 + (i sqrt(3))/2 or x = 5/2 - (i sqrt(3))/2

find the exact value of cos -pi/3
The exact value of cos (-pi/3) can be found using the unit circle or the angle addition formula.
Using the unit circle, we know that the x-coordinate of the point on the unit circle that corresponds to an angle of -pi/3 is cos(-pi/3) and y-coordinate is sin(-pi/3).
On the unit circle, the angle of -pi/3 is the same as the angle of 2pi/3 (since the unit circle has a period of 2pi), therefore the x-coordinate of the point on the unit circle that corresponds to an angle of -pi/3 is -1/2.
Alternatively, using the angle addition formula:
cos (-pi/3) = cos(pi - pi/3) = cos(pi) * cos (pi/3) - sin(pi) * sin(pi/3) = -1/2
So, the exact value of cos (-pi/3) is -1/2.

The intercepts of the graph are
x-intercepts are -4/3, 1, 3y-intercept is 72How to determine the intercepts of the graphThe polynomial is given as
G(x) = -2(3x+4)(x-1)(x-3)^2
Rewrite as
G(x) = -2(3x+4)(x-1)(x-3)²
The x-intercepts of a polynomial are the points at which the polynomial crosses the x-axis.
To find the x-intercepts, we need to set y = 0 and solve for x.
-2(3x+4)(x-1)(x-3)² = 0
Divide through by -1
(3x+4)(x-1)(x-3)² = 0
Now we can solve for each factor equal to zero:
3x+4 = 0, x = -1.33
x-1 = 0, x = 1
x-3 = 0, x = 3
So the x-intercepts are -4/3, 1, 3
The y-intercept of a polynomial is the point at which the polynomial crosses the y-axis.
For this polynomial, we have
G(0) = -2(30+4)(0-1)(0-3)² = -2(4)(-1)(9) = 72
So the y-intercept is (0, 72)

The dynamic equation for conversion to z-scores in real-time is, Z = (Xᵢ - µ )/standard deviations (s)
Z-Score : A Z-Score is a metric that represents that how closely a value relates to mean of set of values. If Z score value is zero that means data point's scores are same as mean score.
Formula for Z- Score is Z = (X - µ)/σ
where, X ---> data values
µ --> mean of values
σ --> standard deviation
For 32, Z = (X - µ)/σ = (32 - 44)/8 = -1.50
For 42 , Z= (X- µ)/σ = (42 - 44)/8 = -0.25
For 48, Z = ( 48 - 44)/8 = 0.5
For 52, Z = ( 52 - 44)/8 = 1.0
For 54, Z = (54 - 44)/8 = 1.25
When we move One standard deviations to right , that means X = 44 + 8 = 52 , So the Z-Score for 52 is Z = 1.0. Hence, required value is 1.0.
