Question

Given that f(x) = 6x + 2 and g(x) = 2x + 4 5 solve for g(f(1)). 1 03 4 8

Answer 1

Answer:

20

Step-by-step explanation:

So we have:

$f(x)=6x+2 \text{ and } g(x)=2x+4$

And we want to find:

$g(f(1))$

So, let's find f(1) first:

$f(x)=6x+2\\f(1)=6(1)+2$

Multiply:

$f(1)=6+2$

Add:

$f(1)=8$

So, f(1) is 8. Substitute this for g(f(1)):

$g(f(1))=g(8)$

Substitute:

$g(x)=2x+4\\g(8)=2(8)+4$

Multiply:

$g(8)=16+4$

Add:

$g(8)=g(f(1))=20$

So our answer is 20
