Question

The following function is an even function. f(x) = 4x^2 − 2

Answer 1

Is this true

Answer 2

Do you see any odd exponents? It might be more obvious in this almost equivalent form: f(x) = 4x^2 - 2x^0

Answer 3

Function is even function if \(f(x) = f(-x)\)

Answer 4

Plug in -x then simplify, if you get original function, then yeah, it is even function

Answer 5

so this is true then

Answer 6

Yep

Answer 7

because i got the same thing

Answer 8

1) Well, then why didn't you show us your work?
2) If that's what you managed, and then it was subsequently demonstrated by another, why do you still doubt?
