Question

What is the inverse function of y = (x – 7)?

Answer 1

(0,-7)

Explanation:

Graph the line using the slope and y-intercept, or two points.

Slope: 1

y-intercept:

(0,−7)

Answer 2

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x+7 f - 1 ( x ) = x + 7 is the inverse of f(x)=x−7 f ( x ) = x - 7 .

hope this helps.
