Water coming out from a fountain is modeled by the function f(x) = −x2 + 5x + 4 where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds. What does the average rate of change of f(x) from x = 3 to x = 5 represent? The water falls down with an average speed of 3 feet per second from 3 seconds to 5 seconds. The water falls down with an average speed of 5 feet per second from 3 seconds to 5 seconds. The water travels an average distance of 3 feet from 3 seconds to 5 seconds. The water travels an average distance of 5 feet from 3 seconds to 5 seconds.
What does the average rate of change of f(x) from x = 3 to x = 5 represent? change in y f(5) - f(3) divided by change in x slope of the line between 5 and 3
this is just a sketch
Is the answer c?
no not c
There is no answer with 2 in it.
read the options again and remember average
So the answer is B?
There is no answers with 6 and 2.
how many seconds from 3 seconds to 5 seconds
how to you find average speed?
the answer is D.
My distance was not 5 ft I had a distance of 6 ft how did you get a distance of 5 ft ?
