Given that f(x) = 2x + 5 and g(x) = x − 7, solve for f(g(x)) when x = −3.


−15
−8
10
25

Answer 1

g(x) = x-7

g(-3) = -3 - 7 ... replace every x with -3

g(-3) = _______ (fill in the blank)

Answer 2

-10

Answer 3

yep

Answer 4

so saying f(g(-3)) is the same as saying f(-10)

I replaced the g(-3) with -10 since the two are equal

Answer 5

hmm...

Answer 6

now evaluate f(-10)
