The curve y=p+qx-2x^2 passes through the point a ((7,6) and (-1,-2). how do i find what p and q are? i tried to differentiate to have one unknown variable, but that doesn't work. so how do i approach this the best way?

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
