Question

f(x) = 3x^2 - 7x + 23 for x = -2.

Answer 1

Given the function:

$f(x)=3x^2-7x+23$

Let's solve for f(x) when x = -2.

To find f(x) when x = -2, substitute -2 for x in the equation and evaluate.

Thus, we have:

$\begin{gathered} f(x)=3x^2-7x+23 \\ \\ f(-2)=3(-2)^2-7(-2)+23 \end{gathered}$

Solving further:

$\begin{gathered} f(-2)=3(4)-7(-2)+23 \\ \\ f(2)=12-(-14)+23 \\ \\ f(2)=12+14+23 \\ \\ f(2)=49 \end{gathered}$

ANSWER:

49
