SOLUTION: The book gives an example of a function for X that substituts 1/2 for X in the expression....
f(1/2)=(1/2)^3 - 3(1/2)^2 + (1/2) + 5
=1/8 - 3(1/4) + 1/2 + 5
=1/8 - 3/4 + 1/

Question 146614: The book gives an example of a function for X that substituts 1/2 for X in the expression....
f(1/2)=(1/2)^3 - 3(1/2)^2 + (1/2) + 5
=1/8 - 3(1/4) + 1/2 + 5
=1/8 - 3/4 + 1/2 +5
=1/8 - 6/8 +4/8 + 40/8
= 39/8
Now im sure this is just simple addition and subtraction with fractions, but I haven't worked with math in many years.
Can someone break down
f(X) = 2X^3 - X^2 + 3X - 2
with f(-1/2) substuting for X please, the more info the better. Answer by Fombitz(32388) (Show Source):

To add and subtract fractions, you need to have a common denominator.
Change all fraction to common denominator of 8.
