31. The graph of which function is always below the graph of the function y (x + 1)2 + 1? O y = 1– (x +1)² O y = 1– (x – 1)² O y = (x – 1)² +1 O y = 2(x + 1)² – 1 7 Oy = =+

Graph both functions on one set of axes. f(x) = (3) * O -4 4 and g(x) = 1.5* -2 -2 y 2 y 6 4 2 f 2 2 4 X X 4 -2 -2 y 6 4 2 y 6 4 2 2 2 g 4 4 X X

6. Select the correct graph below of the function: (x) = x*(x + 2)(x – 2). List the x-intercepts. For each, state its multiplicity and why each either crosses the x- axis or simply touches the x-axis in terms of its multiplicity being odd or even. This problem is worth 8 points with 4 points for the graph selection and 4 points for the explanation of the intercepts.
