Question

Could someone help me out please I don’t know how to

Answer 1

As per given by the question,

There are given that ,

`4y^2+y-9,\text{ when y=-3}`

Now,

There are given y=-3.

So,

Substitute the value -3 instead of y in given equation,

Then,

From the equation,

`4y^2+y-9`

Put the value of y in given equation,

`4y^2+y-9=4(-3)^2+(-3)-9`

Now, solve the above equation,

`\begin{gathered} 4y^2+y-9=4(-3)^2+(-3)-9 \\ =4(9)-3-9 \\ =36-3-9 \\ =36-12 \\ =24 \end{gathered}`

Hence, the value of given equation is 24.
