the function graphed approximates the height of a nail, in meters, x seconds after a construction worker drops it from a skyscraper. after about how many seconds is the nail 50 m above the ground? 3.2 s 3.5 s 3.9 s 4.1 s
Answer
# Explanation:
## Step1: Locate 50 on y - axis
Find the value of 50 on the vertical axis (height $y = f(x)$).
## Step2: Read corresponding x - value
Draw a horizontal line from $y = 50$ to the curve and then a vertical line down to the x - axis. Estimate the x - value. From the graph, when $y=50$, the x - value is approximately 3.9.
# Answer:
3.9 s
