Question

Number 19

Answer 1

If you plug the two points into the given equation, you will have two equations with 2 variables.\[3=A+B(1-1)+C(1-1)(1+1)\]
\[3=A+B(0)+C(0)(2)\]
\[3=A\]

Answer 2

Now let's try the other point.

Answer 3

\[17=3+C(-1-1)+C(-1-1)(-1+1)\]
\[17=3+B(-2)+C(-2)(0)\]
\[17=3-2B\]
\[14=-2B\]
\[-7=B\]

Answer 4

So A = 3 and B = -7
