Problem 43

(1 point) Evaluate the limit lim f (x + h) - f(x) h for each of the following functions at each of the following x-values. If a limit is not defined, enter "DNE". h-0 f(x) = x2, x=-9 lim f(x + h) - f(x) h-0 h f(x) = 1/x, x=-9 lim f(x + h)- f(x) h+0 h f(x) = V4x +7, x=0 lim f(x+ h)- f(x) = h-0 h
