Find {a} the rate of change of y with respect to x and (In) the retative rate of change at 3;. At the given val-ue 01 x, find [c] the rate of change at y, {d1 the relative rate of change of yr, and {e} the percentage rate of change of y. y=x2+5x1;x=2 [a] The rate of change ofywith respect to x is :l. (Simplify your answer. Type an expression using x as the variable.)
