F(x)=4x2-3x+5 f(2) find function value
Dovator [93]

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.
