Which of the following equations describes the graph? a. y = -3×^2 + 4b. y = 3×^2 + 4c. y = 3×^2 - 4d. y = -3×^2 - 4

C. y = 3×^2 - 4

Step-by-step explanation:

Remember that to evaluate a graph when you have options you just ahve to calculate the Y and x intersect, so the grap will intersect with the Y axis when x=0, evaluate Y=3x^2-4 when x=0

y=3(0)^2-4

y=-4

So the graph will touch y when it is at -4. That makes this ecuation the correct for the graph given.

Remember too that when the sign of x is negative the grph grows downward, since this is growing upward the sign of X should be positive.
