f(-x)=x^2+5

To find f(x), we need to substitute -x into the given expression f(-x) and solve for x.

f(-x) = (-x)^2 + 5
= x^2 + 5

Therefore, f(x) = x^2 + 5

To find the value of f(-x), you need to substitute -x into the given equation x^2 + 5.

Substituting -x into the equation, we get:
f(-x) = (-x)^2 + 5

Simplifying the expression:
f(-x) = x^2 + 5

So, f(-x) is equal to x^2 + 5.

To find the value of f(-x) in the given function f(-x) = x^2 + 5, we need to substitute -x into the function in place of x and simplify.

Step 1: Replace x with -x in the given function
f(-x) = (-x)^2 + 5

Step 2: Simplify the expression
f(-x) = x^2 + 5

Therefore, f(-x) = x^2 + 5.

The explanation above walks you through the steps to obtain the value of f(-x) in the given function.
