Answer:  The correct option is (C) 8x^2-x-4.

Step-by-step explanation:  Given two functions f(x) and g(x) as follows :

f(x)=5x^2-2x,\\\\g(x)=3x^2+x-4.

We are to find the value of (f+g)(x).

We have

(f+g)(x)\\\\=f(x)+g(x)\\\\=(5x^2-2x)+(3x^2+x-4)\\\\=5x^2-2x+3x^2+x-4\\\\=8x^2-x-4.

Thus,

(f+g)(x)=8x^2-x-4.

Option (C) is the correct option.

It's the 3rd option. All your doing to me, is adding all the numbers straight down. I think you meant to write it like this: 8x² - x - 4

A) all values at which h has a local maximum <br> B ) all local maximum values of h
Harlamova29_29 [7]

For the given function h(x), we have:

a) at x = -2 and x = 2.

b) y = 0 and y = 3.

<h3>How to identify the maximums of function h(x)?</h3>

First, we want to get the values of x at which we have maximums. To do that, we need to see the value in the horizontal axis at where we have maximums.

By looking at the horizontal axis, we can see that the maximums are at:

x = -2 and at x = 2.

Now we want to get the maximum values, to do that, we need to look at the values in the vertical axis.

  • The first maximum value is at y = 0 (the one for x = -2)
  • The second maximum is at y = 3 (the one for x = 2).

If you want to learn more about maximums:
