[latex]f(x)[/latex] is a fancy term for saying [latex]y[/latex]. It is mainly used in Trigonometry, Pre-Calculus, Calculus, and beyond. [latex]f(x) = 2x^2 + 5\sqrt{x+2}[/latex] plug in the [latex]2[/latex] into the [latex]x[/latex]. [latex] f(2)= 2(2)^2 + 5\sqrt{2+2}[/latex] this gives: [latex] f(2) = 8 + 5\sqrt{4}[/latex] square the 4. [latex] f(2) = 8 + 5(2) [/latex] multiply [latex] 5 [/latex] and [latex] 2 [/latex]. [latex] f(2) = 8 + 10 [/latex] add them together. [latex] f(2) = 18 [/latex] Glad to help.
