9. Use the given functions to evaluate the following. f = {(1,3), (2,5), (-3,8),(5,7),(-7,0) }
g={(0,1),(-3,0),(1,2),(3,-9),(4,6)}
h = {(0,-7), (1,-4), (3,15), (7,7) }
(a) (fºg)(1)
(b) (h+ 9)(3)
(c) f + 2(2)
(d) (hof g)o
10.
Use the diagram to write the following expressions:
(a) f(-a)
(b) 3f(b)-f(-a)
(c) h(-a)
(d) (hop-a)
