Question

Which of the graphs below would result if you made the leading term of the following function negative?

F(x) = 5x^3 + x - 8

Answer 1

I believe the answer is Graph D

Answer 2

Graph D

Explanation:

Given is the function

f(x) =
`5x^3+x-8`

When leading term is changed to negative we get new function

g(x) =
`-5x^3+x-8`

To find y intercept:

Put x=0

Y intercept = 5(0)+0-8 =-8

Since only graph D has y intercept -8, we get graph D is the answer.
