Graph each function.

7. y = − 5 x y equals negative , 5 to the x
8. y = ( 1 2 ) x y equals . open , 1 half , close to the x
9. y = 2 ( 4 ) x y equals 2 . open 4 close to the x
10. y = − 9 ( 3 ) x y equals negative 9 . open 3 close to the x
11. y = 3 ( 2 ) x y equals 3 . open 2 close to the x
12. y = 24 ( 1 2 ) x y equals 24 . open , 1 half , close to the x
13. y = − 4 x y equals negative , 4 to the x
14. y = − ( 1 3 ) x y equals negative . open , 1 third , close to the x
15. y = 2 ( 3 2 ) x y equals 2 . open , 3 halves , close to the x

See Problem 2.

Graph each function as a transformation of its parent function.

16. y = 2 x + 5 y equals , 2 to the x , plus 5
17. y = 5 ( 1 3 ) x − 8 y equals 5 . open , 1 third , close to the x . minus 8
18. y = − ( 0.3 ) x − 2 y equals negative . open 0.3 close super x minus 2 end super
19. y = − 2 ( 5 ) x + 3 y equals negative 2 . open 5 close super x plus 3 end super
20. y = 3 ( 2 ) x − 1 + 4 y equals 3 . open 2 close super x minus 1 end super . plus 4
21. y = − 2 ( 3 ) x + 1 − 5 y equals negative 2 . open 3 close super x plus 1 end super . minus 5
