# Thread: Testing for Eveness and Oddness---- Graphical Solution

1. ## Testing for Eveness and Oddness---- Graphical Solution

Hello, I know this problem could be done Algebraically however the problem asks us to use a calculator.

"Use a graphing utility to graph the function and determine whether its even, odd, or neither."

f(x)= 3x-2

I know how to graph it, but I don't exactly understand what I'm looking for once it's graphed to determine whether or not it is even, odd, or neither.

Thanks for any help!

the graph of an even function is symmetric to the y-axis. (the graph folds onto itself with the fold crease on the y-axis)

the graph of an odd function is symmetric to the origin. (invert the entire graph and it looks the same)

if a function has no such symmetry as described above, then it is a "neither" function.

Thank you very much, I appreciate it.
