Raffle tickets are being sold for a fundraiser. The relationship between n, number of raffle tickets sold, and A, amount of money in dollars raised, is given by the function below.

A(n) = 3n - 15

What is the equation of the inverse function N(a)?
a.N(a) = a+15/3
b. N(a) = a-15/3
c. N(a) = a/3-15
d.N(a) = a/3+15

Answer 1

To find the inverse of a function
i). rewrite y = f(x) or in the case of the above equation, y = A(n),
ii). interchange x and y,
iii). solve for y
