Answer:

(f\circ g)(x)= x + 4

Step-by-step explanation:

<u>Composite Function</u>

Given f(x) and g(x) as real functions, the composite function (f\circ g)(x) is defined as:

(f\circ g)(x)=f(g(x))

It can be found by substituting g into f.

We are given the functions:

f(x) = -x + 3

g(x) = -x -1

Find

(f\circ g)(x)=f(g(x))= - (-x -1) + 3

Removing parentheses:

(f\circ g)(x)= x + 1 + 3

Simplifying:

\mathbf{(f\circ g)(x)= x + 4}

If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!
