Question

Determine if the following function is odd, even, or neither.
f(x) = -5x2 + 3x - 1

Answer 1

what is the value of x?

Answer 2

This function is neither. A function is odd if f(-x) = -f(x); the function will be even if f(-x) = f(x).

Answer 3

the value of x is not important here. all you need to look at is the polynomial

this function is even because it has y axis symetry

Answer 4

it would look something like this

Answer 5

f(-x) = 5x2+3x-1
f(-x) =5(-x)+3(-x)-1
f(-x)= -5x2-3x-1
f(-x)= -(5x2-3x-1)
f(-x) = -f(x)
so it is odd function
