Let f and g be two functions. Given that (f ∘g)(x) = g – 1 (x) = [tex]\frac{x+1}{2} , where x ∈ℝ find an expression for f (x).

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.
