Answer:
1) (f +g) (2) = 8
2) (g- f) (-1) = 3
Step-by-step explanation:
Here, from the given table:
f(2) = 5, g(2) = 3
and f(-1) -3 , and g(-1) = 0
USING (f ± g)(x) = f(x) ± g(x)
To find:
(a) (f +g) (2) = f(2) + g(2)
= 5+ 3 = 8
⇒(f +g) (2) = 8
(b) (g- f) (-1) = g(-1) - f(-1)
= 0- (-3) = 0 + 3 = 3
⇒ (g- f) (-1) = 3
