Assume f(x) = x2 + 3. Find the functional value requested.

f(-7) =

To find the functional value of f(-7), we need to substitute -7 into the function f(x) = x^2 + 3.

1. Start with the given function: f(x) = x^2 + 3.
2. Replace x with -7: f(-7) = (-7)^2 + 3.
3. Simplify the expression: f(-7) = 49 + 3.
4. Compute the sum: f(-7) = 52.

Therefore, the functional value of f(-7) is 52.
