~Hello! I will try to help you!

Given : -

  • f(x) = (x + 2)²
  • f(x) = (x + 2)(x + 2)
  • f(x) = x² + 4x + 4

To Find : -

  • f(5) = ?

Step-by-step Step-by-step explanation : -


\Rightarrow \sf f(x) = {x}^(2) + 4x + 4

»Just substitute the value 5 into the function f(x) above, then:-


\Rightarrow \sf f(5) = {5}^(2) + 4(5) + 4 \\ \Rightarrow \sf f(5) = 25 + 20 + 4 \\ \Rightarrow \sf f(5) = \bf49

With this it's done!
