Answer:
4
Step-by-step explanation:
The function is of even degree. You can tell this because the end behavior is the same at both ends.
There are at least 4 zeros. There are 2 zeros of multiplicity 1 and one zero of multiplicity 2.
The crossings of the x-axis at x=-2 and x=3 have no flat spot, so the multiplicity must be 1; not 3, 5, or some other odd number.
You can tell the zero at x=1 is even multiplicity, because the graph does not cross the x-axis there. You can tell the multiplicity is only 2 because the curve is not flat enough for it to be 4 or more.
A polynomial function with 4 real zeros has a minimum degree of 4.

4. Angles ACB and ECD are congruent as vertical angles. Angles BAC and DEC are congruent (given), then ΔABC and ΔEDC are similar by AA theorem.
5. MN=NP=8 (given), NR=NQ=8+10=18 (given), angle N is common, then ΔNMP and ΔNQR are similar by SAS theorem.
