Find the solutions. Find the Vertex and Max (-1, 0) (5, 0) (2, 10)

All reals All reals (-2, 0) (1, 0) (0, -4) Find the following
3. Domain: 4. Range: 5. Zeros: 6. y-intercepts: All reals All reals (-2, 0) (1, 0) (0, -4)

Find the following: 7. Domain and Range: 8. Zeros and y intercept: 9. Min

Domain and Range: Graph
Look horizontally: What x-values are contained in the graph? That’s your domain! Look vertically: What y-values are contained in the graph? That’s your range!

Domain and Range: Graph

Domain and Range: Graph

Domain and Range: Graph
(-4,-3)

Maximum and Minimum Maximum value: the highest y value seen in the data or on the graph. Minimum value: the lowest y value seen in the data or on the graph.

Max and Min: Graph

Zeros: Graph

Max and Min: Graph

Increasing and Decreasing: Graph
To find where the graph is increasing and decreasing trace the graph with your finger from left to right. Specify x-values! If your finger is going up, the graph is increasing. If your finger is going down, the graph is decreasing.

Increasing and Decreasing

End Behavior: Graph The value a function, f(x), approaches when x is extremely large (∞) or when x is extremely small (-∞).

End Behavior -∞

End Behavior

Average Rate of Change The average range of change between any two points (x1,f(x1)) and (x2,f(x2)) is the SLOPE of the line through the 2 points.

Example 1 Find the average rate of change of f(x) = x3 – 3x when x1= -2 and x2 = 0.
