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]
