The function X-2 is differentiable everywhere on the real line? |

Answer» Answer: To SHOW that F is differentiable at all x∈R, we must show that f′(x) EXISTS at all x∈R. Recall that f is differentiable at x if limh→0f(x+h)−f(x)h exists. And so we see that f is differentiable at all x∈R with derivative f′(x)=−5. hope it HELPS u #NAWABZAADI |
