Suppose that hx f composition gx Complete the following tab
Suppose that h(x) = (f composition g)(x). Complete the following table
Solution
h(x)=(fog)(x)
at x=1
fog(1)= f(g(1))
And g(1)=0
Therefore (fog)(1)= f(g(0))= f(1)=1
therefore h(1)= fog(1)=1
at x=2
h(2)= fog(2)= f(g(2))
and g(2)=1
f(g(2))= f(1)= 9
therefore h(2)= fog(2)= 9
and it is given that h(0)=9
h(0)= f(g(0))=5
and g(0)=2
Therefore f(g(0))=5
f(2)=9
| x | f(x) | g(x) | h(x) |
| 0 | 1 | 2 | 5 |
| 1 | 9 | 0 | 1 |
| 2 | 5 | 1 | 9 |
