Let y = f(x) = 11x – 7. When y = 48 in the original function, what is the value of y in the inverse function?
A 5
B 4
C-4
D 7

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
