Question

What is the inverse of H(x)=1/2x+3

Answer 1

Answer:

x=-6

Step-by-step explanation:

Answer 2

Answer:

$h^{-1}$ (x) = 2x - 6

Step-by-step explanation:

let y = h(x) and rearrange making x the subject

y = $\frac{1}{2}$ x + 3 ( multiply through by 2 to clear the fraction )

2y = x + 6 ( subtract 6 from both sides )

2y - 6 = x

Change y back into terms of x with x = $h^{-1}$ (x)

$h^{-1}$ (x) = 2x - 6
