F(x)=-4x-6 and g(x)=3x+5. Find (f o g)(-3) pl hel

Step-by-step explanation:

f(x) = - 4x - 6

g(x)=3x+5

To find (f o g)(-3) we must first find

(f o g)(x)

To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)

That's

(f o g)(x) = - 4( 3x + 5) - 6

= - 12x - 20 - 6

(f o g)(x)= - 12x - 26

Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve

We have

(f o g)(-3) = - 12(-3) - 26

= 36 - 26

We have the final answer as

(f o g)(-3) = 10

Hope this helps you
