Group 6 Flashcard Quiz Quant


In the prepswift even/odd function video, greg said that any function with only even or only odd exponents is an even or odd function respectively. How is |x| even when it’s exponent is 1?
I understand that f(-x)=f(x) but it does not have any even powers

When it’s a polynomial. |x| isn’t; and even then, work from the definition of an even function.
