Given: f(x) = x- 7 and h(x) = 2x + 3<br> Write the rule for f(h(xc)).

ivolga24 [154]

Answer:

$f(h(xc)) = 2xc-4$

Step-by-step explanation:

Given

$f(x) = x - 7$

$h(x) = 2x + 3$

Required

$f(h(xc))$

First, calculate h(xc)

If $h(x) = 2x + 3$

Then

$h(xc) = 2xc + 3$

Solving further:

$f(x) = x - 7$

Substitute h(xc) for x

$f(h(xc)) = h(xc) - 7$

Substitute $h(xc) = 2xc + 3$

$f(h(xc)) = 2xc + 3 - 7$

$f(h(xc)) = 2xc-4$
