To find the x-intercept(s) of the function, we set f(x) equal to 0 and solve for x:
-16x^2 + 25x = 0
Factoring out x, we get:
x(-16x + 25) = 0
Setting each factor equal to 0 gives us two possible x-intercepts:
x = 0 or -16x + 25 = 0
The first x-intercept is 0, which means the soccer ball starts at the ground (x = 0) before it is kicked.
To find the second x-intercept, we solve the equation -16x + 25 = 0:
-16x = -25
x = -25/-16
x ≈ 1.563
So the x-intercept is approximately (1.563, 0), and the correct interpretation is:
A. (1.563,0) ; The soccer ball will return to the ground 1.563 seconds after it has been kicked.
-16x^2 + 25x = 0
