Answer:
a) f(2) = 4
b) g(3) = 3
c) g(1/3) = -1
d) f(3) = 1/2
e) g(-2) = 2
f) f(π) = 3
Explanation:
We are given:
f={(2,4),(-4,3),(3,1/2),(π,3)} and g={(3,3),(-2,2),(1/3,-1)}
We need to find the following values of f and g
a) f(2)
f(2) means when x=2, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =2 then y=4
So, f(2) = 4
b) g(3)
g(3) means when x=3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =3 then y=3
So, g(3) = 3
c) g(1/3)
g(1/3) means when x=1/3, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =1/3 then y=-1
So, g(3) = -1
d) f(3)
f(3) means when x=3, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =3 then y=1/2
So, f(3) = 1/2
e) g(-2)
g(-2) means when x=-2, we need to find the value of y.
Looking at the given g={(3,3),(-2,2),(1/3,-1)}, when x =-2 then y=2
So, g(-2) = 2
f) f(π)
f(π) means when x=π, we need to find the value of y.
Looking at the given f={(2,4),(-4,3),(3,1/2),(π,3)} , when x =π then y=3
So, f(π) = 3
