Given f(x) = ax - b, what is f^-1(x)?

A)

Step-by-step explanation:

f(x) = ax + b

y = ax + b

x = ay + b

ay = x - b

y = (x - b)/a

f^-1(x) = (x - b)/a

A)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
