What are the domain and range of the function f(x)= x4 - 2x2-4?
O domain: all real numbers
range: all real numbers greater than or equal to -5
O domain: all real numbers
range: all real numbers greater than or equal to -4
domain: all real numbers between -2.5 and 2.5
range: all real numbers
O domain: all real numbers between -2.5 and 2.5
range: all real numbers greater than or equal to -5
Answer: A. domain: all real numbers
range: all real numbers greater than or equal to -5
The domain and range of the function f(x)= x4 - 2x2-4 is all real numbers, and all real numbers greater than or equal to -5.
What is the domain and range of the function?The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.
We are given that;
f(x)= x4 - 2x2-4
Now,
To find the range, we can consider the behavior of the function as x approaches positive or negative infinity. As x gets very large or very small, the x^4 term will dominate, and the function will become very large (positive for large positive x, negative for large negative x). So, we know that the range is not all real numbers.
We can also complete the square to rewrite the function in vertex form:
f(x) = (x^2 - 1)^2 - 5
From this form, we can see that the minimum value of f(x) is -5, which occurs when x = 0. Therefore, the range of the function is:
Range: all real numbers greater than or equal to -5
So, the answer will be Domain: all real numbers, Range: all real numbers greater than or equal to -5

5. The daily temperature recorded (in degree F) at a place during a week was as under:
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
35.5
30.8
27.3
32.1
23.8
29.9
Find the mean temperature.
Answer:
29.9 °F
Step-by-step explanation:
The formular for mean is given as;
Mean = Sum of Terms / Number of terms
Number of terms = 6
Sum of terms = 35.5 + 30.8 + 27.3 + 32.1 + 23.8 + 29.9 = 179.4
Mean = 179.4 / 6 = 29.9

Answer:
I hope I can help
Step-by-step explanation:
welcome po
A high-speed elevator can rise 480 feet in 3 seconds. Which expression represents the rate, in feet per minute, of the elevator?
Answer:1 minute = 60 seconds
60 seconds/3 seconds = 20
480 feet x 20 = 9,600 feet
The elevetor travels 9,600 feet per minute.

Answer:
The larger angle <K, has a measure of 120 degrees.
Step-by-step explanation:
So, a supplementary angle are two or more angles that combine to form a 180 degree straight line. So here, we need to set up an algebra equation.
2x = the larger angle (because it's two times the smaller angle)
x = the smaller angle
So then, you need to set both equal to 180 degrees, since combine they equal 180 degrees
2x + x = 180
3x = 180
x = 60
Using basic algebra, we see that the smaller angle is 60 degrees, but wee need to find the larger angle. Remember, we represented the larger angle as 2x.
2 time 60 is 120, so the larger angle is 120 degrees

In ABC, angle C is a right angle. Which statement must be true
Answer:
a
Step-by-step explanation:
a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13
this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13
