Answer: Try the 2nd one maybe?
Step-by-step explanation:
Because
using the vertical line test
Graph b is a function
gravity is 32.17 ft/sec
1454 ÷ 32.17 = 45.20 seconds = answer
This describes a parabolic path that starts at x=0 on a value of y = -5.1. That's when the rock is below ground in the hole. To find the answer we need to know the second x axis crossing. The first is when it is rising and reaches ground level, the second is after it peaks and falls back to the ground and lands. Using the quadratic formula I get the two zeros of this function to be about
x= 15.29, and 66.71. The rock then lands 66.71 feet from him horizontally.
