You need to substitute (-5) into your function everywhere the x appears, sub it in, and solve for y. Or if you have a graph you need to look at the x-axis at 5, and look up and down to see where the graphed function is at that point.
To find the value of f(-5), we need to know the value of the function f(x). Since the function is not provided, we cannot determine the exact value of f(-5). Is there any additional information or context that can be provided to help determine the value of f(-5)?
