Problema Solution
The change in water level of one portion of the Mississippi River is about -0.3 ft per day. If the water level starts at 17 feet and falls for x days, the level is represented ny the function f(x)= 17 - 0.3x.
Find the intercept and graph the function.
What does each intercept represent?
Answer provided by our tutors
f(x)= 17 - 0.3x.
let f(x)=y
y=17 - 0.3x.
to find x intercept
put y=0
x= 56.66=change in watre level
to find y intercept put x=0
we gets
y= 17= water level
