Is this function even or odd

f(x)=2x+5
It'd odd I think because when I substitue -x it becomes -f(x) right?

All the answers so far are wrong.
The function is neither even or odd.
An even function satisfies f(x) = f(-x)
for all x.
But f(3) <> f(-3).
An odd function is symmetric
around the origin and satisfies
f(x) = -f(-x).
But f(3) = 11
-f(-3) = -(-1) = 1.
Examples of odd functions are
y = x and y = x^3.

2 times any number will always be even, and then an even add an odd (Which is the 5) always gives an odd number, so the function is odd!

The highest degree of the function is x^1. Since 1 is an odd number, the function is odd.

Yep!!!
