Given the function:
[tex]f(x)=3x^2-7x+23[/tex]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:
[tex]\begin{gathered} f(x)=3x^2-7x+23 \\ \\ f(-2)=3(-2)^2-7(-2)+23 \end{gathered}[/tex]Solving further:
[tex]\begin{gathered} f(-2)=3(4)-7(-2)+23 \\ \\ f(2)=12-(-14)+23 \\ \\ f(2)=12+14+23 \\ \\ f(2)=49 \end{gathered}[/tex]ANSWER:
49
