Question

given the quadratic equation y = 5x^2 + 8x + 9, solve for the y-coordinate of the parabola when x = -3

Answer 1

[AI-generated answer — Bot GPT 3.5]

To solve for the y-coordinate, we substitute x = -3 into the equation y = 5x^2 + 8x + 9:

y = 5(-3)^2 + 8(-3) + 9
y = 5(9) - 24 + 9
y = 45 - 24 + 9
y = 30

Therefore, the y-coordinate of the parabola when x = -3 is 30.
