Given f(x) = -3x - 7 and g(x) = x4, choose
the expression for (fºg)(x).

x^8+7x^4

Step-by-step explanation:

First we have to do the g(x) cause it's closest to x.

g(x)=x^4

x^4 is the output for g(x) ad input for f(x). So now we have to put it in x's place in here➡️f(x)

So, f(x^4)=(x^4)^2+ 7(x^4)

=x^8+7x^4

It's the final output

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
