Question

!!! Help Please
Determine if the function f(x)=x^2l5xl is odd, even, or neither. I need help to start and finish it. please help

Answer 1

are you able to find f(-x) ?

Answer 2

Do you know the first step?

Answer 3

My notes are just not of help. and f(-x) do I just replace the x with a -x?

Answer 4

every x with -x, yes

Answer 5

Im sure I did this wrong but I think -5x^3?

Answer 6

f(x)=x^2l5xl

f(-x)=(-x)^2l5(-x)l

f(-x)=(-x)^2l-1*5xl

f(-x)=(-x)^2l-1|*|5xl

f(-x)=(-x)^2*(1)*|5xl

f(-x)=x^2*|5xl

Answer 7

So because f(-x) = f(x), we can say that f(x) is an even function

Answer 8

Ohh ok I got it and took note thank you!
