A 10-Review Name________________________________BDFM?________Why?_______________________________AStd9b: I can determine if a representation is a function and state its domain and range.Find the domain and range. 1. 2. 3.
Graph. Find the domain and range. 4. y=√x+9 5. y=x2+8 x+7 6. y=−x2+6 x
Solve for x7. by factoring 02092 xx 8. using the quadratic formula 5 x

Draw a curve with the given restrictions.9. x-values: The curve lives between -4 and -1.y-values: The curve lives between -8 and -2
10. x-values: The curve lives between 4 and ∞ .y-values: The curve lives between 3 and ∞
11. x-values: The curve lives between -∞ and ∞ .y-values: The curve lives between −∞ and 7
Consider the following equations, and calculate or solve accordingly. f (x)=√x−9 g ( x )=x2−9 h ( x )=−9 x+3
12. h(12) 13. f ( x )=4 14. g(−3)
15. h ( x )=−15 16. f (13) 17. g ( x )=72
