I'm not sure if this is legit, but the range of the whole function is the union of sets (3, 7], (4, 8], (18, 66] or (3, 7] U (4, 8] U (18, 66]Īm I making myself clear? Please correct me if I made any mistakes. Now you can find the other clauses' y values the same way. What is the range of this clause? that would be 3 < y <= 7 or it can be expressed more 'mathy' as y or the range of the clause = (3, 7] (this means all real values from 3 to 7 (3 is not included, 7 included)) But anyway, for example, we had a piecewise function like this :įind the range of each clause separately.įor 2x+3, 0 < x <= 2, since this is a straight line (with a slope), you just need to find the y values for the endpoints. I don't know if you had done this or not by saying "guess and check for the domain".

Square root functions are useful in physics when modeling curvature of certain geometric figures.This answer is a year late, I'm also new to this topic, but I'll try to answer.An ability to graph and recognize graphs quickly will increase proficiency in the calculus which studies rates of changes of functions.Students can come up with an equation for the piecewise function if they can come up with an equation for each piece of the function, and an interval over which each piece is defined.

Looking at the graph of the function y = f ( x ), students should notice that it comes in two pieces.

Various functions can show up on this exercise, such as polynomials, conics and exponentials.

An open dot is a whereas a closed dot indicates less than or equal or greater than or equal.

One way to always create a graph is to create a T-table of values.

However, using a T-table is all that is necessary.

Knowledge of writing domains and some of the parent graphs of common functions are encouraged to ensure success on this exercise. The student is asked to select the correct equation for the graph from the multiple choice list provided.

Find the correct formula: This problem provides a graph of a nonlinear piecewise function.

There is one type of problem in this exercise: This exercise practice finding the formula of a nonlinear piecewise function, given its graph. The Graphs of nonlinear piecewise functions exercise appears under the Algebra II Math Mission.
