I need help. Please be organized with the answers. Thank you

1. Determine the x-coordinates of all points on the function f(x) = x3 + 3x2 5x + 2, where the slope of the tangent Is 4. 2. Determine the equation of the tangent line to the curve f(x) = x100 + 100x, when x = 1. 3. The motion of a particle is defined by the function 5(t), where s is the displacement from the origin in meters aftert seconds. a) If s'(2) = 0, then what do you know ab0ut the motion of the particle at t = 2? b) If s"(4) = -5 and s'(4) = -10, then draw a sketch of what the graph of s(t) could look like around t = 4
