Lesson 3
Using Function Notation
 Let’s use function notation to talk about points.
3.1: Which One Doesn’t Belong: Function Notation
Which one doesn’t belong?
 \(f(0) = 2\)
 \((0,5)\)
 \(y = x+2\)
3.2: Points into Function Notation and Back
 A function is given by the equation \(y = f(x)\). Write each of these coordinate pairs in function notation.
 \((2,3)\)
 \((\text{}1,4)\)
 \((0,3)\)
 \((4,0)\)
 \(\left( \frac{2}{3}, \frac{3}{4} \right)\)
 A function is given by the equation \(h(x) = 5x  3\). Write the coordinate pair for the point associated with the given values in function notation.
 \(h(3)\)
 \(h(\text{}4)\)
 \(h\left( \frac{2}{5} \right)\)
3.3: A Graph with Properties

Draw a graph of function \(y = g(x)\) that has these properties:
 \(g(0) = 2\)
 \(g(1) = 3\)
 \((2,3)\) is on the graph
 \(g(5) = \text{}1\)

Han draws this graph for \(g(x)\). What is the error?
