Answer
The value of \[f\left( 4 \right)\]is \[30\].
Work Step by Step
The provided equation is\[y=3{{x}^{2}}-5x+2\].
To find the value of \[f\left( 4 \right)\], substitute the value \[x=4\] in the provided equation.
\[\begin{align}
& y=3{{\left( 4 \right)}^{2}}-5\left( 4 \right)+2 \\
& =48-20+2 \\
& =30
\end{align}\]
