For the two functions f(x) and g(x) what is the value of g(f(3))

Question

X     f(x)              X     g(x)

-5      7               -2        3

-2     -5                 1      -1

1       3                 2      -3

3       2                 3      -5

Answer 1

Hi Kelly,

 

When working with compound function, work from the inside out.

 

So we first evaluated f(3)

Use that result as the "x" 

Then evaluate g("x")

 

f(3) = 2

g(2) = -3

 

So g(f(3)) = -3
