2. Polynomial Functions

3. C)Solutions Use the APP!! Change order to 3 Enter 3, 4, 0, -5 x-intercept is (0.870, 0) D)x-intercept(s) Same as the solution(s) 0.870 E)Zeroes Same as the solution(s) 0.870 F)Roots Same as the solution(s) 0.870 G)y-intercept(s) Use the TABLE!! You have already entered function into the y= window to look at the graph. 2 nd Graph, look at where x = 0. y-intercept is at (0, -5)

4. Polynomial Functions H)Period(s) of Increase I)Period(s) of Decrease Find the turning points. One is a relative maximum Use 2 nd Trace 4 to find the maximum. The x-value for the relative maximum is -.889 when rounded to 3 decimals. One is a relative minimum. Use 2 nd Trace 3 to find the minimum. The x-value for the relative minimum is 0.

5. Polynomial Functions

9. C)x-intercept(s), Solutions, Zeroes, Roots On this graph, you can visually tell that the graph touches the x-axis at -4 and 2. The x-intercepts are (-4,0) and (2,0) D)y-intercept(s) Look at the table for x = 0 to see that y = 64. The y-intercept is (0,64)

10. Polynomial Functions E)Period(s) of Increase Find the turning points. These are identifiable by just looking at the graph. The first turning point is at (-4,0). The second turning point is at (-1,80) The third turning point is at (2,0)
