As per given by the question,
There are given that ,
[tex]4y^2+y-9,\text{ when y=-3}[/tex]
Now,
There are given y=-3.
So,
Substitute the value -3 instead of y in given equation,
Then,
From the equation,
[tex]4y^2+y-9[/tex]
Put the value of y in given equation,
[tex]4y^2+y-9=4(-3)^2+(-3)-9[/tex]
Now, solve the above equation,
[tex]\begin{gathered} 4y^2+y-9=4(-3)^2+(-3)-9 \\ =4(9)-3-9 \\ =36-3-9 \\ =36-12 \\ =24 \end{gathered}[/tex]
Hence, the value of given equation is 24.
