What is the equation, in standard form, of a parabola that models the values in the table?
x
–2
0
4
f(x)
0
–6
78
Of the given points, (-2,0), (0,-6), (4,78)
only (0,-6) would satisfy the robots equation,
so as usual for more than straight-forward question,
the robot tutor is wrong
try y = 4x^2 + 5x - 6
