Question 155609: Choose the statement that is true about the given quantities:

A. The quantity in column A is greater
B. The quantity in column B is greater
C. The two quantity are equal
D. The relationship cannot be determined from the given information

Column A : f(3) where f(x) = 2x -7, if x < = 1
= -x + 9, if x > 1

Column B: f(2) where f(x) = x + 2, if x < 8
= 3x -3, if x > = 8

Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!

f(3) is asking: "if x=3, then f(3)=? "

Since 3 is greater than 1, this means that we'll use the second equation

Start with the second equation

Plug in

Add

So

-------------------

f(2) is asking: "if x=2, then f(2)=? "

Since 2 is less than 8, this means that we'll use the first equation

Start with the first equation

Plug in

Add

So

--------------------------

Since , this means that the value of column A is greater than the value of column B. So the answer is A.
