Radical Functions Tutoring FAQ
Radical functions are graphable equations that contain a variable (typically denoted as x) underneath a radical sign (√). Many people mistakenly call this symbol a "square root sign," but in truth it can be used for any root if a subscript number is present on the outside. If you or your child need a little help graphing radical functions, Varsity Tutors can refer you to a radical functions tutor to help you reach your economic goals.
Here are some of the concepts that may be reviewed during radical functions tutoring sessions:
Simplifying Radical Functions (to make them easier to graph)
Clues in an Expression to Determine What a Graph Looks Like
Many radical function tutoring sessions begin by making sure that a student knows the terminology involved. Let's look at y=√x as an example. This expression is saying that value y needs to be multiplied by itself twice to equal the value of the "radicand" inside the radical symbol, x. If we change the equation to y=3√x, the new subscript number (three) means that value y must be multiplied by itself three times in order to be equivalent to x.
Once the basics are down, your radical functions tutor may start sharing some tricks to help your child visualize what a graph might look like before they graph it. For example, any function with a subscript greater than one will expand the resulting graph vertically, while a value between zero and one shrinks it vertically. If there is any math besides the radical (say y=√x +2), the domain starts at two and works its way forward from there.
Working with a private tutor also confers the advantages of individualized attention. Students are free to learn at their own pace, as a topic never needs to be left behind before a student is ready to do so. Sessions may be adapted to a child's learning style to make study sessions more engaging and interesting.
