MTH 122 Test 2 Review 4.1 – 4.7 1. Given 5 2 12 6 ) ( 2 3 + - - = x x x x f a) Neatly sketch a graph of the function. Label any local maxima, local minima, absolute maxima, absolute minima, x-intercept(s) and y-intercept(s). b) Determine the intervals where the function is increasing. c) Determine the intervals where the function is decreasing. 2. Complete the graph of y = f(x) if it is a function which is symmetric with respect to the origin. Label 4 additional points on the graph. All points are integers. 3. Given the graph of f(x) below, determine the number of turning points and number of x-intercepts. What is the minimum degree of the graph? List any local and absolute extrema. Is the graph even, odd or neither? Is the leading coefficient positive or negative? Why?
