Explain what happens as the value of a increases. In mathematics and more specifically in graph theory a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related. You can graph thousands of equations and there are different formulas for each one.
Graphs help us understand different aspects of the function which would be difficult to understand by just looking at the function itself.
So same vertex same line of symmetry same zeros. Remember sqrt x tells you to use the principal root which is the positive root. You can graph thousands of equations and there are different formulas for each one. It has the unique feature that you can save your work as a URL website link.
