Answer 1

Answer:

Step-by-step explanation:

In the quadratic

$3x^2+2x-8$ the sign on the leading coefficient is positive, so the parabola opens upwards. The y-intercept exists where the x's are equal to 0, so the y-intercept is (0, -8). Match that to the table that has those characteristics in it.
