Let f(x) = 5x + 12. Find f−1(x)

f⁻¹(x) = (x - 12)/5

Step-by-step explanation:

To find the inverse of f(x), you have to switch the places of the x and y.  You then have to rearrange the equation so that it is equal to y.

f(x) = 5x + 12

x = 5y + 12

x - 12 = (5y + 12) - 12

x - 12 = 5y

(x - 12)/5 = 5y/5

(x - 12)/5 = y

f⁻¹(x) = (x - 12)/5

total of apples - take away four

6-4 = 2

answer is 2 apples

x= 3^y
