Learning Target: I can apply my knowledge of inverse variations to solve problems.

• 4 - I can teach it!

• 3 - I understand it.

• 2 - I'm getting there.

• 1 - I don't understand, I need some more help.

These first 4 questions are checking for understanding

1. How are inverse variations related to the reciprocal function?

2. Explain why the amount of propane in a grill’s tank and the time spent grilling could represent an inverse variation.

3. Why is it impossible for the graph of the function  $y=\frac{1}{x}$   to intersect the horizontal asymptote at the x-axis?
