How would you define what a function is?
A function represents an equation for the area underneath the curve on a graph.
What is the meaning of an exponential value and how is it represented?
An exponential value expresses how many times a number is multiplied by itself. This is represented by showing the amount of times the number is being multiplied as a small script number, at the top right of the number that's being multiplied. For example, "5 exponential 2" means that 5 is being multiplied by itself twice (5 x 5 = 25). Or "5 squared."
