need help to solve, plese see attached

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) = 4 - 7x Step 1: f ( x + h ) = Step 2: f ( x + h) - f(x) = Step 3: f ( x + h) - f(x) h Step 4: f'(x) = lim f ( x + h) - f(x) = h -0 h 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 + 9x Step 1: f ( x + h ) = Step 2: f( x + h) - f (x) = Step 3: f( x + h) - f(x) h Step 4: f'(x) = lim f ( x + h ) - f(x ) h- 0 h
