Graphs of Functions - Exercise 1
For the function f(x) = x4 - 4x2, solve x4
- 4x2 = 0 in order to find the x-intercepts, justifying
steps in finding these intercepts. Find points on each side of each
x-intercept, placing values in the table below. Graph this
function on your graphing calculator. Be able to explain why f(x) is
even, show the points you generated, and show a sketch of the graph.
Is f(x) an even function? Why or why not?
|f(x) = x4 - 4x2
Solve x4 - 4x2 = 0
