The population of valley heights is decreasing at a rate of 10% per year. Can this be modeled using a linear function? Why or why not?
Explain please
Explain please

No, because the slope of the curve is dependent on the value of y
dy/dt = -0.1y
ln(y) = -0.1t + lnYo
y = Yoe^(-0.1t) : an exponential function.
dy/dt must be a constant value for y to be a linear function.
dy/dt = -0.1y
ln(y) = -0.1t + lnYo
y = Yoe^(-0.1t) : an exponential function.
dy/dt must be a constant value for y to be a linear function.

NO!
You are modeling the equation, if I get the phrase correct: y= x*.9^r. Where y = population of the year you are seeking, r is the number of year from the starting year where you took your census population, and x is the total population you start out or the census population. R will always be the variable because time is a variable likely to be on your x-axis if you get my thrift of thoughts.

It cannot because it's a compound equation
