Evaluate the function when x=3, x=0, x=-2
a. f(x) = x
b. g(x)= 4x-1
c. f(x) =1/3x+2/3
a. f(x) = x
When x=3:
f(3) = 3
When x=0:
f(0) = 0
When x=-2:
f(-2) = -2
b. g(x)= 4x-1
When x=3:
g(3) = 4(3) - 1 = 12 - 1 = 11
When x=0:
g(0) = 4(0) - 1 = 0 - 1 = -1
When x=-2:
g(-2) = 4(-2) - 1 = -8 - 1 = -9
c. f(x) =1/3x+2/3
When x=3:
f(3) = (1/3)(3) + 2/3 = 1 + 2/3 = 1 2/3
When x=0:
f(0) = (1/3)(0) + 2/3 = 0 + 2/3 = 2/3
When x=-2:
f(-2) = (1/3)(-2) + 2/3 = -2/3 + 2/3 = 0
