Question

Given h, left bracket, x, right bracket, equals, 2, x, plus, 4h(x)=2x+4, find h, left bracket, minus, 1, right bracketh(−1).

Answer 1

To find h(x) - 1, we substitute -1 for x in the equation:

h(x-1) = 2(x-1) + 4

Simplifying this expression:

h(x-1) = 2x - 2 + 4

= 2x + 2

Therefore, h(-1) = 2(-1) + 2 = -2 + 2 = 0
