is even, odd or neither.

Determine Function Type: To determine if the function $f(x)$ is even, odd, or neither, we need to compare $f(x)$ with $f(-x)$ . If $f(-x) = f(x)$ , then the function is even. If $f(-x) = -f(x)$ , then the function is odd. If neither condition is met, the function is neither even nor odd.
Substitute $-x$ in Function: First, let's find $f(-x)$ by substituting $-x$ for $x$ in the function $f(x)=x^6+7x^2-1$ . $\newline$ $f(-x)=(-x)^6+7(-x)^2-1$
Simplify $f(-x)$ Expression: Now, simplify the expression for $f(-x)$ .
$f(-x)=(-x)^6+7(-x)^2-1$
$f(-x)=x^6+7x^2-1$
Compare $f(x)$ and $f(-x)$ : We have: $f(x)=x^6+7x^2-1$ $f(-x)=x^6+7x^2-1$ Since $f(-x) = f(x)$ , the function $f(x)$ is an even function.
