Question

Given h(x)=-x+2h(x)=−x+2, find h(4)h(4).

Answer 1

(-4 + 2 • h(4))^2

Explanation:

h(4)h(4)

↓

h(4) • h(4) = (-4 +2 • h(4)) • (-4 +2 • h(4))

↓

Calculate

(-4+2× h(4)) × (-4+2× h(4))

Simplify using exponent rule with same base

a^n • a^m = a^n+m

(-4+2× h(4))^2

I hope this helps out.
