Evaluate f(x) = 4x + 3x^2 − 5 when x = -2.<br> 23<br><br><br> -1<br><br><br> -25<br><br><br> -49
frozen [14]

Answer:

f(-2) = -1

Step-by-step explanation:

One way of doing this is to substitute -2 for x in every place where x shows up:

f(x) = 4x + 3x^2 − 5  →  f(-2) = 4(-2) + 3(-2)^2 − 5  

                                 → f(-2)  = -8    + 3(4) -   5, or f(-2) = 4 - 5, or f(-2) = -1
