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
