How do you determine if f(x)=7 is an even or odd function?

2 Answers

"7" is an odd number

Explanation:

Please follow the following steps:

1) Divide the given numerical number by 2.
2) If the answer is real number , such as 3.5, then we have odd number.
3) If the answer is integer number, such as 3, then we have an even number.

Examples:
A) "7"/"2" = 3.5 is areal or odd number
B) "6"/"2" = 3 is an integer or even number

f(x) = 7 is an even function.

Explanation:

  • A function f(x) is even if f(-x) = f(x) for all x in the domain of f(x).

  • A function f(x) is odd if f(-x) = -f(x) for all x in the domain of f(x)

In our example, with f(x) = 7 we find:

f(-x) = 7 = f(x)

for all x

So f(x) is even.
