How to create a graph of c when...

Answer 1

@phi @satellite73

Answer 2

I graphed \(1.75x, \text{if} \text{ } 0 \le x \le 9\)

Answer 3

But I wasn't sure how to include \(1.25x, \text{if} \text{ } x \ge 10\) with the first one.

Answer 4

this is a piecewise function
Its telling you to graph the function 1.75x from x=0 to 9 and then graph the function 1.25x from ten to infinity

Answer 5

So if there are 10 pencils, it would cost $12.50.

Answer 6

yup

Answer 7

Let's assume that this is my graph:


Do I just plot it like that?
