find a real-life application of a quadratic function. State the application, give the equation of the quadratic function, and state what the x and y in the application represent. Choose at least two values of x to input into your function and find the corresponding y for each. State, in words, what each x and y means in terms of your real-life application

Firstly get t using dy/ds....u must get t range between 0 and 240. That t is substitute into the equation. Settle!

A real-life application of a quadratic function can be seen in the trajectory of a projectile. Let's consider the example of a basketball being thrown into the air.

The equation of a quadratic function that represents the height (y) of the basketball above the ground in terms of time (x) can be given by:
y = -4.9x^2 + 10x + 1.5

In this equation, the variable x represents time in seconds, and y represents the height of the basketball above the ground in meters.

Let's find the corresponding y-values for two different x-values:

For x = 1 second:
y = -4.9(1)^2 + 10(1) + 1.5
y ≈ 6.6 meters

For x = 2 seconds:
y = -4.9(2)^2 + 10(2) + 1.5
y ≈ 8.4 meters

In this application, the x-values represent the time elapsed in seconds, and the y-values represent the vertical height of the basketball in meters. For example, when x = 1 second, the corresponding y-value of approximately 6.6 meters means that the basketball is at a height of 6.6 meters above the ground after 1 second of being thrown. Similarly, when x = 2 seconds, the corresponding y-value of approximately 8.4 meters indicates that the basketball has reached a height of 8.4 meters above the ground after 2 seconds.
