Even

Step-by-step explanation

make:


\begin{gathered} f(x) \\ \text{and} \\ f(-x) \end{gathered}

If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even. If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd, then

Step 1


f(x)=c\text{ ( a constant)}

and


f(-x)=c\text{ ( a constant)}

Hence


\begin{gathered} f(x)=f(-x) \\ \text{then the function is EVEN} \end{gathered}

Step 2

graph

I hope this helps you
