Evaluate the function when x=3, x=0, x=-2

f(x) = x
g(x)= 4x-1
f(x) =1/3x+2/3

When x=3:
f(x) = x = 3

g(x) = 4x - 1 = 4(3) - 1 = 12 - 1 = 11

f(x) = 1/3x + 2/3 = 1/3(3) + 2/3 = 1 + 2/3 = 5/3

When x=0:
f(x) = x = 0

g(x) = 4x - 1 = 4(0) - 1 = 0 - 1 = -1

f(x) = 1/3x + 2/3 = 1/3(0) + 2/3 = 0 + 2/3 = 2/3

When x=-2:
f(x) = x = -2

g(x) = 4x - 1 = 4(-2) - 1 = -8 - 1 = -9

f(x) = 1/3x + 2/3 = 1/3(-2) + 2/3 = -2/3 + 2/3 = 0
