[tex]\begin{gathered} \text{Given} \\ 4x^2-5 \\ \end{gathered}[/tex]
To evaluate the given at x = 3, substitute x by 3, and evaluate the expression accordingly
[tex]\begin{gathered} 4x^2-5 \\ =4(3)^2-5 \\ =4(9)-5 \\ =36-5 \\ =31 \end{gathered}[/tex]
Therefore, the value of the given at x = 3, is 31.
