Question

Найди координаты точки пересечения графика функции y=−16x2+18x−30 с осью ординат

Answer 1

Ответ:

(0; -30)

Объяснение:

y=−16x²+18x−30

пересечение с осью ординат означает х = 0

у(0) = -30

координаты точки пересечения (0; -30)

Answer 2

Finding the Coordinates of the Intersection Point

To find the coordinates of the intersection point of the function \(y = -16x^2 + 18x - 30\) with the y-axis, we need to find the point where the graph of the function intersects the y-axis. This point will have an x-coordinate of 0, as it lies on the y-axis.

The y-coordinate of the intersection point can be found by substituting \(x = 0\) into the function \(y = -16x^2 + 18x - 30\).

Substituting \(x = 0\) into the function: \[y = -16(0)^2 + 18(0) - 30\] \[y = -30\]

So, the coordinates of the intersection point with the y-axis are (0, -30).

This information is based on the mathematical principles of finding the y-intercept of a function, and the calculation is derived from the given function \(y = -16x^2 + 18x - 30\).
