There are two local minima and one local maximum, which are all found between -1 and 2.5.
Since it is a quartic with a positive leading coefficient, you can expect the curve to look like the letter W.
If you like, you can post your answer for verification.
The polynomial function f is defined by f(x)x^4-3x^3-2x^2+4x+5.
Use a graphing calculator to find all the points (x,f(x)) where there is a local maximum.
