$2.$ Next to the above lines, create a simple class named $$Quadratic$$ that has the following members.

$$ three public variables of int type, a$,$ b$,$ and c$.$ Set the value of a to $2,$ b to $-3,$ and c to $15.$

$$ one public function named $$func$()$ of double type that takes one parameter named $$x$$ of double type and

performs a calculation based on func$($x$)=$ ax$2+$bx$+$c$.$

$3.$ In the $$main$()$ function, create an instance of the $$Quadratic$$ class named $$q$1$ and then use it to call the

$$func$()$ function by passing four values: $3,3\mathrm{.}14,-3,$ and $-3\mathrm{.}14.$ Make sure the output looks similar to the

following.

x value

$324$

$3\mathrm{.}1425\mathrm{.}2992$

$-342$

$-3\mathrm{.}1444\mathrm{.}1392$
