1. Use a graphing utility to graph the function and to approximate any relative minimum or relative
maximum values of the function. (Round your answers to the nearest integer. If an answer does
not exist, enter DNE.)
y = x^3 - 6x^2 + 13
relative minimum (x, y) = (_______________)
relative maximum (x, y) = (________________)
Solution
If you are using a TI-84 Calculator, you can press the "Y=" button and type in "x^3-6x^2+13"
under "Y1". Then press the "Graph" and a graph should appear. To find the exact relatives
maximum and minimum values, press "2nd" and then the "Trace" buttom and select
"minimum" or "maximum". Choose any point to the left of the minimum or maximum, and
click "Enter". Then choose any point to the right of the minimum or maximum and click
"Enter" again. The y-value is the relative min or max. Relative min = -19 Relative max = 14
