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 and calculate the result.
Step 1: Replace x with -7 in the function f(x):
f(-7) = (-7)^2 + 3
Step 2: Simplify the expression:
f(-7) = 49 + 3
Step 3: Perform the addition:
f(-7) = 52
Therefore, the functional value of f(-7) is 52.
