Question

If a function is defined by the equation y = 1/2x -3/2 , which equation defines the inverse of this function?

Answer 1

Answer:

B

Step-by-step explanation:

Rearrange the equation making x the subject

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

2y = x - 3 ( add 3 to both sides )

2y + 3 = x

Change y back into terms of x with x being the inverse function, that is

y = 2x + 3 → B
