Question
Curve Fitting Find real numbers $a, b,$ and $c$ so that the graph of the function $y=a x^{2}+b x+c$ contains the points $(-1,-2),(1,-4),$ and (2,4)
Step 1
For point (-1, -2): -2 = a(-1)^2 + b(-1) + c For point (1, -4): -4 = a(1)^2 + b(1) + c For point (2, 4): 4 = a(2)^2 + b(2) + c Show more…
