Use the four-step process to find the slope of the tangent line to the graph of the given function at any point. (Simplify your answers completely.) f(x) = x + 6x Step 1: Step 2: Step 3: f(x + h) = f(x + h) f(x) = f(x + h) - f(x) h What should you replace x with when finding f(x + h)? Click the Read It link to review the concepts you need. x Step 4: f'(x) = lim f(x + h) - f(x) = h0 h x
