Question

Given the function f(x)=5(x+4)-6, solve for the inverse function when x=19

Answer 1

When 4/5
You multiply it by having 60:4 and divided it4/6

Answer 2

Y = 5(x+4)-6

x = 5(y+4)-6

x = 5y +20 - 6

x= 5y +14

5y = x-14

y = (x-14)/5

when x = 19, y = (19-14)/5

y = 5/5

y=1

In short, Your Answer would be Option 2

Hope this helps!
