Question

Given the quadratic equation y = 5x2 + 8x + 9 so for the y-coordinate of the parabola when x = -3

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the y-coordinate of the parabola when x = -3, we need to substitute -3 into the equation for x:

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

Simplifying,

y = 5(9) - 24 + 9

y = 45 - 24 + 9

y = 30

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