We are given that
[tex]f(x)=-8x^2-3x+4[/tex]
We want to find
[tex]f(-3)[/tex]
Solution
From
[tex]f(x)=-8x^2-3x+4[/tex]
To find f(-3), we only need to put x = -3
[tex]\begin{gathered} f(x)=-8x^2-3x+4 \\ \text{put x = -3} \\ f(x)=-8x^2-3x+4 \\ f(-3)=-8(-3)^2-3(-3)+4_{} \\ f(-3)=-8(9)+9+4 \\ f(-3)=-72+13 \\ f(-3)=-59 \end{gathered}[/tex]
Therefore, f(-3) = -59
