Question

Which of the following is a point you can generate to create the parabola for the quadratic equation y=−6x2+3x+8
?(1 point)

(−6,8)


(−3,323)


(−6,206)


(−3,−55)

Answer 1

Plug x = -3 into y = -6x^2 + 3x + 8:
y = -6(-3)^2 + 3(-3) + 8 = -6(9) - 9 + 8 = -54 - 9 + 8 = -55.
So (−3, −55) is on the parabola.
