Answer :

[tex]f(x)[/tex] is a fancy term for saying [tex]y[/tex]. It is mainly used in Trigonometry, Pre-Calculus, Calculus, and beyond.

[tex]f(x) = 2x^2 + 5\sqrt{x+2}[/tex]

plug in the [tex]2[/tex] into the [tex]x[/tex].

[tex] f(2)= 2(2)^2 + 5\sqrt{2+2}[/tex]

this gives:

[tex] f(2) = 8 + 5\sqrt{4}[/tex]

square the 4.

[tex] f(2) = 8 + 5(2) [/tex]

multiply [tex] 5 [/tex] and [tex] 2 [/tex].

[tex] f(2) = 8 + 10 [/tex]

add them together.

[tex] f(2) = 18 [/tex]

Glad to help.
