Question

Given f(x)=x-7 and h(x)=2x+3 write the rule for f(h(x))

Answer 1

Answer:

2x - 4

Step-by-step explanation:

It is given that,

f(x) = x - 7 and,

h(x) = 2x + 3

Therefore, f(h(x)) = f(2x + 3)

                            = (2x + 3) - 7

                            = 2x - 4

That is, what ever the function is inside the outer function,

we need to substitute the value of x in the outer function with the inner function.
