Question

If line p represents the function f(x) = 3x− 5, line represents f -1(x).

Answer 1

y = (1/3)x + 5/3

Explanation:

The inverse function can be found by swappint x and y, then solving for y.

... given: y = 3x -5

... with variables swapped: x = 3y -5

Solve for y: add 5, divide by 3.

... x + 5 = 3y

... (1/3)x +5/3 = y
