1. Your own story problem that uses exponentials. Some topics you can use are listed below. 2. Create an exponential function for your story problem.
3. You must create a table of at least 5 points using your exponential function.
4. Is your function an example of exponential growth or decay, how do you know?
5. Create a graph either using your table of values from #3, or using graphing technology.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
