Hello,  To solve this function for f(4) we need to plug 4 into f(x) and the result will be our answer. We know that f(x) is [latex]3x^2-7[/latex]. Plugging in 4 we get [latex]3(4)^2-7=41[/latex]. Therefore, f(4)=41. Hope this helps!

What the question is asking you to do is plug in 4 in place of x in the given equation:  [latex]f (x) = 3(4)^2-7 [/latex] [latex]4^2=16*3-17=41[/latex] Final answer: 41
