Use the graph to evaluate the expression f g0 Solution1 f

Use the graph to evaluate the expression. (f + g)(0) =

1) (f + g)(0) = f(0) + g(0)

==> (f + g)(0) = 1 + 2 = 3

Hence (f + g)(0) = 3

2) (f - g)(-1) = f(-1) - g(-1)

==> (f - g)(-1) = 0 - 3 = -3

Hence (f - g)(-1) = -3

3) (fg)(1) = f(1) * g(1)

==> (fg)(1) = (2)(1) = 2

Hence (fg)(1) = 2

4) (f/g)(3) = f(3) / g(3)

==> (f/g)(3) = 4/(-1) = -4

Hence (f/g)(3) = -4
