  1. 7.9 Square Root Functions and Inequalities Algebra II w/ trig

  2. If you understand the patterns that take place when graphing a function, then graphing becomes a quick and painless process. Let’s look at the parent graph f(x) = √x or y = √x Domain: x > 0 Range: y > 0 General equation: y = a √(x-h) + k where a, h, and k effect the pl appearance of the graph

  3. General equation: y = a √(x-h) + k Again, (h, k) is your starting point as in absolute value and quadratic equations. *Remember to take the opposite of h and k as you see it. Also, the a terms works like the rise part of your slope and the run is always 1. You can also make a table to find more points on the graph.
