Instructions: Solve the following inequalities. Express your answers in interval notation.

Two tasks in the problem. One quadratic and one rational. In both tasks, vary use of <, >, <=, and >= (even though I don't in my examples).

Task 1 is a quadratic inequality that can be factored fairly easily. Pull from examples like the following (but without any scaffolding):

Task 2 is a rational inequality. Stick to whole numbers for the partition numbers. Pull from examples like the following:

I think for Task 1, I would prefer to have them so that it does not already have 0 on one side - so more like Activities 1.7.5 and 1.7.6.

Do we want to add something about "expressing the solution graphically" somewhere? The objective is for them to give the solution graphically and in interval notation. Or maybe give a possible solution and have them explain/show why it is (or is not) a solution?
