Let g(x)=2x-4 and evaluate g(1/3)

Question

Let g(x)=2x-4 and evaluate g(1/3)

Answer 1

g(x) = 2x - 4

g(1/3) = 2(1/3) - 4          substitute value

g(1/3) = 2/3 - 4              multiply

g(1/3) = 2/3 - 12/3         LCD

g(1/3) = -10/3               combine like terms

Answer 2

g(1/3)= 2(1/3)-4 = 2/3 -4 = 2/3 -12/3= -10/3 

Answer 3

g(x) = 2x - 4

 

To get g(1/3), just substitute 1/3 for x in the expression, and simplify.

 

g(1/3) = 2(1/3) - 4 = 2/3 - 4 = 2/3 - (3/3)4 = (2 - 12) / 3 = -10/3
