The quadratic function is 
Step-by-step explanation:
The quadratic function given is 
and same quadratic function is passes through (-3,37), (2,-8), (-1,13)
Replacing points one by one
we get,
For (-3,37) :

=<em> equation 1 </em>
For (2,-8) :

= <em>equation 2</em>
For (-1,13)

= <em>equation 3</em>
Solving the linear equation to get values of a,b,c
Subtract equation 2 with equation 3
we get,
= <em>equation 4</em>
Now, Subtract equation 1 with equation 2
we get,
= <em>equation 5</em>
Now, Add equation 4 with equation 5
we get,
Replacing value of a in <em>equation 5</em>



Replacing value of a and b in <em>equation 1</em>




Thus,
The quadratic function
