F (x) = 4x2-3x+5 f (2) find function value

Hello!

This question is an example of function notation. Function notation is basically f (x), said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F (2) is written as function notation, while x = 2 is not.

F (2) = 4x² - 3x + 5

F (2) = 4 (2) ² - 3 (2) + 5

F (2) = 4 (4) - 6 + 5

F (2) = 16 - 6 + 5

F (2) = 15

Therefore, the value of F (2) is 15.
