I need help. Be organized with the asnwers please. Thank you:

Part 1

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 after t seconds. a) If s'(2) : 0, then what do you know about the motion of the particle at t : 2? b) If 3"(4) = 5 and s'(4) = 10, then draw a sketch of what the graph of 3(t) could look like around t = 4
