Based on the end behaviors, which graph is the graph of f(x) = -2x4 − 4x3 + x2 + x + 3?
Answers
Given:
The function is
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
To find:
The graph of the function by using the end behaviors.
Solution:
We have,
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]
It means, the graph of the function approaches to negative infinity on the both ends.
Therefore, the correct option is C.

EXPLAIN how you would graph the line y = 1/3x + 5
Answers
Answer:
Okay so this is the best way to explain it, its already in y=mx+b form which is the easiest way to graph something, its where m= slope and b=the y-intercept so 1/3 is m so the slope is 1/3 but first we need to mark the y coordinate which is 5, so on your graph dot (0,5) then from that go up 1 and right 3 then that should be your graph!!! I've included pictures to help you know what it should look like.

I need to know X for 8 and 10 if u feel like it. PLS
Answers
Answer:
8) x=9
10) 23 degrees
Step-by-step explanation:
8) vertical angles are congruent to each other so we can set the expressions as such and solve:
7x + 3 = 10x - 24
3 = 3x - 24
27 = 3x
9 = x
10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:
12x + 7 + 6x - 7 = 90
18x + 7 - 7 = 90
18x = 90
x = 5
now we plug it back into the expression equivalent to the measure of angle O:
6(5) -7
30 - 7
23 degrees
6. The total cost of materials to build the foam
pit is $1,285.20. What is the cost of materials
per square foot?
Answers
Answer:
Cost of Material per square foot = $1.7
Step-by-step explanation:
Given:
Length = 24
Width = 12
Height = 6.5
Find:
Cost of Material per square foot
Computation:
TSA of pit = 2[bh + hl] + lb
TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)
TSA of pit = 2[78+156] + 288
TSA of pit = 756 square foot
Cost of Material per square foot = 1,285.20 / 756
Cost of Material per square foot = $1.7

Answers
Answer: $335,633
Step-by-step explanation:
First find the number of years difference:
= 2025 - 1985
= 40 years
Use the compound interest formula to find the answer:
= Value * ( 1 + rate) ^ no. of years
= 125,000 * ( 1 + 2.5%)⁴⁰
= $335,633
Jan rode to her friend's house with a constant speed of 14 m/hr. How long will she take to
travel the 15 miles there?
Answers
Answer:
1.07 hours
Step-by-step explanation:
14 miles = 1 hour
15 miles = x hours
Equal these two together
14 mi/1hr = 15 mi/xhr
Cross multiply
14 mi × x hr = 1 hr × 15 mi
I will stop using the units for now so it won't be as confusing
14x = 15
Divide both sides by 14 to isolate the variable
14x ÷ 14 = 15 ÷ 14
x = 1.07... hours

The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.
Answers
Answer:
As "x" increases "y" *decreases*
y as a function of x is not *constant*
Therefore the function is *nonlinear*
For all values of x, the function value y *≥* 0.
The y intercept of the graph is *8*
x=1 function value of y is *5*
