number 97

In Exercises 87-98, for each polynomial function, find
a. The end behavior
b. The y-intercept of its graph
c. The x-intercept(s) of the graph of the function and the multiplicity of each of the real zeros
d. Symmetry of the graph of the function, if any
e. The intervals where the function is positive or negative
Use this information to sketch a graph of the function. Factor first if the expression is not in
factored form.
87. f(x) = x²(x - 1)
89. f(x) = (x - 2)²(x + 2)
91. g(x) = (x + 1)²(x − 2)(x+3)
93. g(x) = 2(x + 1)²(x - 3)²
95. f(x)= x³ + 4x² + 4x
97. h(x)=2x² + 4x³ + 2x²
88. h(x) = x(x - 2)²
90. g(x) = (x + 1)(x - 2)²
92. f(x) = (x - 1)(x + 2)²(x + 1)
94. f(x) = -3(x - 2)²(x + 1)²
96. f(x)= x³ 2x² - x
98. f(x)= 3x4 - 6x³ + 3x²
