2x² + x = 3 at x 4. - Problem 2. Find an equation for the tangent line to the curve y You must use the definition of derivative instead of shortcut formula to find the slop of the tangent line. Problem 3. Use the formula to find the derivative of below functions. 1 5x² 7x + 2 (1) f(x) = ( +x (2 - ?5x+x²), (2) g(x) · = 3x4 Problem 4. Find the second derivative of below functions. (1) f(x) = 4²/1, (2) g(x) = ln(3x² + 2x ? 5). M3 - 9
