The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

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.

Which expression is equal to (f+g)(x)?
