Algebraic-Graphical-Numerical

Determine whether the function is even, odd, or neither.

(a) algebraically,

(b) graphically by using a graphing utility to graph the function,

(c) numerically by using the table feature of the graphing utility to compare f(x) and f(-x) for several values of x.

Question1: f(t)=t^2+2t-3

Question2: f(x)=x* sqrt(1-x^2)
