The function is vertically compresses to get the graph of the function
. So, the function
is:
...(i)
From the given graph it is clear that the graph of the function passes through the point (3,3). So, putting
and
in the above function, we get
Putting in (i), we get
Therefore, the correct option is D.
Answer:
(a) 4.875 minutes
(b) 1.86 minutes
Step-by-step explanation:
The length of fence = 150 feet.
Rate of painting by Tyler = 11ft/min
Rate of painting by Benito = 15ft/min
