If so, assume and all turning points are represented in the graph. a. Determine the minimum degree of the polynomial. b. Determine whether the leading coefficient is positive or negative based on the end behavior and whether the degree of the polynomial is odd or even. c. Approximate the real zeros of the function, and determine if their multiplicities are even or odd Part 1 The graph . represent a polynomial function. Part 2
Explanation / Answer
a.
Minimum degree is 4. As you can see the curve, cut the x-axis twice and touches it at one point. This touch point would feature twice in the root. so in total 4 roots.
c.
Real zeroes : -1, -2, 2, 2
-1 and -2 have odd multiplier while 2 has even multiplier.
Polynomial: (x+1) (x+2) (x-2)2
when the polynomical curve is open upwards it has leading coefficient positive because at inifite, it will become infinite (not negative of infinite)
c.
