Q1: If ax + b is the inverse of the function below, what is the value of a?

Question

f(x) = x + 0.5

Q2: If ax + b is the inverse of the function below, what is the value of b?
f(x) = x + 0.5

Answer 1

Q1: If ax + b is the inverse of the function below, what is the value of a?
f(x) = x + 0.5
so y = x + 0.5
inverse
x = y + 0.5
or
y = 1 x - 0.5 = a x + b
