Answer:
a = 8
r = 15%
When t = 3, y= 4.9
Step-by-step explanation:
8 represents the original amount because that's what you're increasing, so a=8.
To find your percentage, look into the parenthesis to see the decimal. We see that it's 0.15, but that's not a percentage yet, so you have to multiply it by 100. Or, moving your decimal two times to the right. Therefore, r=15%.
Now to find what the function will equal when t=3, simply plug 3 for t. I've always used a calculator for this so I'm not going to write it out (sorry). Your result should be 4.9 (this is already rounded to the nearest tenth for you).
To determine if something is a function or relation, you would look at the x values and determine if every x value has 1 y value. any x vaue with more than one y value would be a relation.
this one would be a function because there only one y value for every x value
