Solving math equations can be challenging, but it's also a great way to improve your problem-solving skills. New: \($22,000\); \(4\) years old: \($14,800\). A relation with this property is called a function14. We can use the given ordered pair solutions to estimate all of the other ordered pairs by drawing a line through the given points. The vertical line represents a value in the domain, and the number of intersections with the graph represent the number of values to which it corresponds. We can also recognize functions as relations where no \(x\)-values are repeated. Given the graph, determine the domain and range and state whether or not it is a function: Domain: \((,15]\); range:\(\); function: no. You can either choose the colors for them to make it unified across the classroom or let them choose their own. 1 0 obj The domain is \(\{4, 2, 0, 3\}\) and the range is \(\{3, 3, 5, 6, 7\}\).
