Question

What is the maximum number of relative extrema contained in the graph of

Answer 1

Step-by-step explanation:

an expression (polynomial) with the highest exponent = n has n zeros (solutions, where y = 0, although some of them can be imaginary numbers, or some can fall together into 1 solution).

and it has max. n-1 relative extrema ("bumps" in the curve, where the curve changes direction from up to down or vice versa).

so, in our case of

f(x) = 3x⁵ - x³ + 4x - 2

we have max. 5-1 = 4 relative extrema.
