Practice problem
How is the function f(x)=x2f(x) = x^2f(x)=x2 related to f(−x)=(−x)2f(-x) = (-x)^2f(−x)=(−x)2?
f(x)+f(−x)=0f(x) + f(-x) = 0f(x)+f(−x)=0 for all real values of xxx
f(x)=f(−x)f(x) = f(-x)f(x)=f(−x) for all real values of xxx
f(x)⋅f(−x)=1f(x) \cdot f(-x) = 1f(x)⋅f(−x)=1 for all real values of xxx
Type a concept, like “slope” or “photosynthesis”.
