We went over word problems for quadratic function/equation.

There are severla types of such problems:

• Questions with area
• Questions with droppoing/throwing object in the air
• Questions with maximum/minimum values
• Questions with right triangles
• Questions with consecutive numbers

In all cases, we need to read carefully from the question, gather the givens, draw a picture to help us understand the problem, label the unknown, and write out equations. Then solving it should be easier as we can always use the formulae to do so.

We went over several such problems in the classroom together. For the homework (below), finish them all.
