Question is included in this file. Thanks for helping!

Suppose a quadratic polynomial be \$f(x)=ax^2+bx+c\$.
Then we know that
\$f(-4)=-22,\$
\$f(-1)=2,\$ and
\$f(2)=-1.\$

Using \$f(-4)=-22,\$ we can deduct that \$16a-4b+c=-22.\$
Using \$f(-1)=2,\$ we can deduct that \$a-b+c=2\$
And finally, using \$f(2)=-1,\$ we can deduct that \$4a+2b+c=-1.\$

I have got a partial answer so far.

What do I do after I find a, b, and c?
