3. [-/4 Points] DETAILS TANAPMATH7 9.3.016.MI. 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 ) = 4x2+ 7x Step 1: f( x + h ) = Step 2: f ( x + h) - f (x ) = f( x + h) - F(x) Step 3: h f( x + h) - f(x) Step 4: F'(x) = lim h
