# Unit 3 Test - Part I **Problem 1:** The problem presents a graph and asks several questions about it: **(a)** Even or odd function? * The function is neither even nor odd. **(b)** Leading coefficient positive or negative? * The leading coefficient is positive. **(c)** Function degree? * The degree of the function is 4. **(d)** Zeros and multiplicity? * Zero: -2, Multiplicity: 1 * Zero: 1, Multiplicity: 3 **(e)** Factored form of the equation? * (x + 2)(x -1) **Problem 2, 3, 4, 5, and 7:** The problems provide various polynomial functions and ask for matching them to their respective graphs. | Function | Graph | |--------------------|--------| | $f(x) = x^{3} - 5x$ | A | | $f(x) = -x^{2} + x + 4$ | F | | $f(x) = -x^{4} + 2x^{2}$ | E | | $f(x) = -x^{5} + 3x^{3} + 1$ | D | | $f(x) = x^{2} + 2x^{2}-4x^{3}+x$ | B | | $f(x) = x^{5} - 3x^{2} + 2$ | C |
