Discuss the range of this problem situation.

• Range of Function:

  All real numbers

• Range of Problem Situation:

  $$x>1$$ because you cannot have a negative or 0 amount of insecticide

• Range of Problem Situation:

  All real numbers because it is the same as the function

• Range of Problem Situation:

  $$x>0$$ because you cannot have a negative amount of insecticide

• Range of Function

Write an equation for each of the three options. Make sure the define your variables.

• Option 1: Put the $1000 in a non-interest bearing account but deposit a minimum of $10 a month.

• Option 2: Deposit the money in an account that earns 10% interest compounded annually.

• Option 3: Deposit the money in an account with a rate of 9% but whose interest is compounded bi-annually (twice a year).

• $$y=1000+10\left(12x\right)$$

• $$y=1000\left(1+0.10\right)^x$$

• $$y=1000\left(1+\frac{0.09}{2}\right)^{2x}$$

Fill in _____ on the line. Then solve using Desmos (a graph, table, or analytic strategy)

​

Page 7b

Go to Desmos. Graph each function. Look for the intersection point to solve this (there will be two points).

To find the points you will need to change your window or zoom way out. Ask how to do this.
