Exam 3: Polynomial and Rational Functions

Find the x-intercepts of the polynomial function. State whether the graph crosses the x-axis, or touches the x-axis and turns around, at each intercept. - $f ( x ) = ( x + 1 ) ( x - 8 ) ( x - 1 ) ^ { 2 }$

Use the Leading Coefficient Test to determine the end behavior of the polynomial function. - $f ( x ) = - x ^ { 2 } ( x - 3 ) ( x + 2 )$

Find the x-intercepts of the polynomial function. State whether the graph crosses the x-axis, or touches the x-axis and turns around, at each intercept. - $f ( x ) = x ^ { 3 } + 11 x ^ { 2 } + 40 x + 48$

The graph of a quadratic function is given. Determine the function's equation. -
