Question

How do you determine if a function is even, odd or neither? y=3x^2+4

Answer 1

Even function: f(x) = f(-x).
Odd function: -f(x) = f(-x)

Answer 2

Your function is Even. Because (-x)^2 = (x)^2

Answer 3

\[f(-x)=\cases{\begin{array}{cl} f(x) & \text{if } f \text{ is even}\\ -f(x) & \text{if } f \text{ is odd}\end{array}}\]

Otherwise neither.

Answer 4

"Because (-x)^2 = (x)^2" how did you figure that out?

Answer 5

Every negative number when is "^2" turns into a positive number
