Finding the Domain and Range of Functions (Lessons 2-1 and 4-1)
Use ONE item from the left to form the domain and range of the function on the right.
All real numbers ≤ 2
All real numbers
All real numbers ≥ -2
All real numbers ≥ 3
All real numbers ≤ 0

Graphing Quadratic Functions (Lesson 4-1)
Graph the quadratic function by hand. Use contrasting colors. When your graph is complete, you may use a graphing calculator to check your work.
f(x)=(x-3)^{2}-5
Question 4

Graphing Quadratic Functions (Lesson 4-1)
Graph the quadratic function. Zoom and pan your graph to establish an appropriate viewing window.
f(x)=2(x-3)^{2}+1
Click the graph tab.
Click on the graph background to add a point. Add two points to create a graph. Drag a point or type in x and y coordinates to edit its position. Click on a point to delete it.

Show your work on the canvas.
You may also complete your work on paper or on a whiteboard and upload a clear picture of it to the canvas.
Question 8
8.
Combining two or more elements forms composite chemical mixtures. In some cases, if you change the order in which you mix two chemicals, it can produce very different results.
A composite function is made by combining two functions. If you are buying a $60 shirt and there is a 50% off sale and you have a $10 coupon, does it make a difference which discount is applied first? If so, which order results in a lower price?
Question 9

One-to-one relationships describe situations where people are matched with unique identifiers, such as their social security numbers.
A function is a relation that matches x-values to y-values. What do you suppose a one-to-one function is?
