Assume f(x) = x2 + 3. Find the functional value requested. f(-5) =

Plug in x=-5

You get 25+3 = 28

To find the functional value of f(-5), we need to substitute -5 into the equation f(x) = x^2 + 3 and evaluate it.

Plug in -5 for x in the equation:
f(-5) = (-5)^2 + 3

Simplify the expression:
f(-5) = 25 + 3

Add the numbers:
f(-5) = 28

Therefore, the functional value of f(-5) is 28.
