Question 67255: To find an equation for the inverse of a function, solve for x in terms of y. Some functions in the form "y=function of x" are preferable, interchange x and y. To find the inverse f(x) = 3x + 6, match each algebraic step with its description.
1. y = 3x + 6
2.x = (y-6)/3 = 1/3(y) - 2
3.y = (1/3)y - 2

a.interchange for x and y

b.solve for x

c.let y = f(x)

To find an equation for the inverse of a function, solve for x in terms of y. Some functions in the form "y=function of x" are preferable, interchange x and y. To find the inverse f(x) = 3x + 6, match each algebraic step with its description.
1. y = 3x + 6.................................C
2.x = (y-6)/3 = 1/3(y) - 2.......................B
3.y = (1/3)y - 2....................................A
