Ashley bought some books for $3 each received a discount of $6 off of her total purchase. She spent $45 after the discount. HOw many books did she but. Write an equation that could be used to answer

Let x equal the number of books bought.

45 = 3x - 6

(This is the answer because $45 is the total price, each book is $3, and $6 is discounted from the actual price.)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
