if f(x)= x+3 / 4 (x+3 over 4), what is the equation for f^–1(x)?
a. f^–1(x) = 4(x  3)
b. f^–1(x) = 4x + 3
c. f^–1(x) = 4(x + 3)
d. f^–1(x) = 4x  3

Best ResponseYou've already chosen the best response.0so the function is \[y = \frac{x + 3}{4}\] to find the inverse swap x and y \[x = \frac{y + 3}{4}\] now make y the subject of the equation
