If g(x) is the inverse of f(x) and f(x) = 4x+12what is g(x)? O g(x) = 12x + 4
O g(x) = 1/4x - 12
O g(x)= x-3
O g(x) = 1/4x - 3

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
