Question

Given: f(x) = x - 7 and h(x) = 2x + 3

Write the rule for h(f(x)).
h(f(x)) = 2x - 11

Answer 1

h(f(x)) = 2x - 11


h(f(x)) = 2x - 7


h(f(x)) = 2x - 4


h(f(x)) = 3x - 4

Answer 2

just substitute the f(x) in place of x inside equation h(x)

so

f(x)=x-7

h(x)= 2x+3

so h(f(x)) = 2(x-7) +3 = 2x-14+3 = 2x-11

h(f(x)) = 2x-11

hope this is understandably sure easy
