Hello, I need help with these practice questions pleasee . Could you do them on a piece of paper or on the practice questions sheets so I can better understand.

Thank you

1 1. Determine the derivative of the following. Leave your final answer in a simplified factored form with positive exponents. a) y = 3+ V5x b) y = nx3 - x" + 12 c) y = (x* + 1)3(2x2 + x - 1) d) y = -2-6 e) y = 3x + V3x + V3x f) y = ((2x3 - 4x) 5-6)712. Determine equation of the tangent to the curve f (x) = = -5x (3x+4)2 at x = -1. 13. Determine the coordinates of the point(s) on f(x) = x3 - 2x2 where the tangent line(s) are perpendicular to y - x + 2 = 0. 14. Determine a quadratic function f(x) = ax + bx + c if its graph passes through the point (2, 19) and it has a horizontal tangent at ( -1, 8). 15. The function f (x) = katz has a horizontal tangent at x = 1. Determine the value of k
