The curve with equation y = 8x² + 2/x has one stationary point. Find the co-ordinates of this stationary point.

What is the inverse of the function f(x)=2x+1

How do i do this activity, is appreciated

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.
