Function: f(x)=x^4-5x+2.

Question

Determine whether the graph of the given function is symmetric with respect to the y-axis, symmetric with respect to the origin, or neither. Use calculator and the standard window to support your conclusion.

Answer 1

A function is symmetric to the y-axis (sometimes called an "even" function), iff f(-x) = f(x).

Is this true for the given function?
