Thanks, some of these I kind of need to refresh up on, lol.

1.

Graph the functions on the same coordinate plane.

f(x)=−2x

g(x)=x^2−3

What are the solutions to the equation f(x)=g(x)?

Options (get each correct one)

−3

−2

0

1

3

2.

Which characteristic is correct for the function f(x)=−2x^3+3x ?

Odd

Even

Neither even nor odd

both even and odd

3.

What is (f+g)(x)?

f(x)=x^2−36

g(x)=x^3+2x^2−10

(f+g)(x)=

Thanks a million!!!!!!!!!!!!!

1. See the graph here, PF : https://www.desmos.com/calculator/xshyczl312

The solutions occur at x = -3 and x = 1

2. 2x^3 + 3x

If we can put -x into the function and come back to what we started with...it is even

So..... 2(-x)^3 + 3(-x) = -2x^3 - 3x = f(-x) ......not what we started with...so..not even

If f(-x) = -f (x) ......then it is odd

-f(x) = - [ 2x^3 + 3x ] = -2x^3 - 3x = f(-x)....so...it's odd

3. (f + g) x means f(x) + g(x) = [ x^2 - 36 ] + [ x^3 + 2x^2 -10 ] = x^3 + 3x^2 - 46
