Section 10.1 Graphing Square Root Functions 545 Comparing Graphs of Square Root Functions Graph gx x 2 . Compare the graph to the graph of f x x . SOLUTION Step 1 Use the domain of g, x 2, to make a table of values. x 23 4 5 6 gx 0 1 1.4 1.7 2 Step 2 Plot the ordered pairs. Step 3 Draw a smooth curve through the points, starting at 2, 0.

The parent function has the point of origin at 0, 0 3 2 x f x 3 2 x f x The graph of this function shifts right 2. The graph of this function shifts left 2. 5 x f x As you can see on the left, the curve is just about the same for a 5 th root, verses a cubed root. This will be the same case for any radical function where the

In the last section we learned how to determine if a relation is a function. The relations we looked at were expressed as a set of ordered pairs, a mapping or an equation. Looking at the result in Example, we can summarize the features of the square function. We call this graph a parabola. As we consider the domain, notice any real number

Here is what the graph of this table looks like The graphs of square root functions are always curved. The curve above looks like half of a parabola lying on its side, and in fact it is. It's half of the parabola that you would get if you graphed the expression y 2 x.And the graph of y x is the other half of that parabola. Notice that if we graph the two separate functions on the

Table and Graph of the Basic Quadratic Function. The techniques we used to graph many of the absolute value functions in Section 1.4 can be applied to quadratic functions, too. In fact, knowing the graph of enables us to graph every quadratic function, but there's some extra work involved. We start with the following theorem

their graphs, and you will solve their equations both graphically and algebraically. Lesson Topics Section 10.1 Roots, Radicals, and Rational Exponents ! Square Roots ! Nth Roots !

For functions involving square roots, ensure the expression under the root is non-negative. Visualize the function graph to help identify the domain and range, especially for common function types. Intercepts of a Function. To find latexxlatex-intercepts, set the function equal to zero and solve for latexxlatex.
