Question

Find dy/dx|x = 7, given that y = 8 - x2. dy/dx|x = 7 = exact number, no tolerance Show that f(x) = { is continuous and differentiable at x = 1. Sketch the graph of f. f is continuous at x = 1, since f is differentiable at x = 1, since Show that f(x) = { is continuous and differentiable at x = 1. Sketch the graph of f. f is continuous at x = 1, since lim x rightarrow 1- f(x) = lim x rightarrow 1+ f(x) = f(1) = f is differentiable at x = 1, since lim h rightarrow 0- f(1 + h) - f(1)/h = lim h rightarrow 0+ f(1 + h) - f(1)/h = f'(1) =
