Answer 2

~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 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!
