Answer:
Your competitor's roller coaster The maximum height of its heel is 80m. Horizontal distance between the starting point and the ending point is about 160m. ... 2) As parabola opens downward, vertex will be its maximum point. 3) Therefore, as the maximum height of its heel is 80m, y value of vertex will be 80.
Step-by-step explanation:
Answer:
The function given is:
P(x) = 15x² + 350x - 2000
or
y = 15x² + 350x - 2000
Interchange x and y:
x = 15y² + 350y - 2000
x = (y√15)² + 2(y√15)(45.19) + (45.19)² - (45.19)² - 2000
x = ( y√15 + 45.19)² - 4042.14
( y√15 + 45.19)² = x + 4042.14
Take square root:
y√15 + 45.19 = (√(x + 4042.14))
y√15 = (√(x + 4042.14)) - 45.19


The minimum value of x, for which function is defined and real, is x= -4042.14
Hence, the range of inverse is x ≥ -4042.14
