let f(x)= x^2  1. evaluate f(x)at x=6, 6

pre calculus 
MathMate,
f(x)=x^21
f(6)=(6)^21=361=37
f(6)=(6)^21=361=37
So we see that for this particular function, f(6)=f(6).
In fact, since f(x) is an even function (consisting of even powers of x), this property of f(x)=f(x) is true for all values of x.
You can try out other pairs, such as f(2) and f(2) to verify this property.
