Given f(x) = 5x - 6 and g(x) = x2 - 5x + 6, find the function (f - g)(x). Use the ^ key for the exponent. Enter your answer as the following example: -2x^2+3x+10.

Question

idk im really confussed  where to even start

mathmale · Answer

f(x) = 5x - 6 and g(x) = x2 - 5x + 6 are separate functions.
Your job is to subtract the 2nd function from the first; we know this because we're supposed to evaluate (f-g)(x).

Write

  f(x) =              5x - 6 
-g(x) = -( x2 - 5x + 6)
----    ------------

Here we have four columns.  

The first column can be written as f(x)-g(x).

Find the sums of the second, third and fourth columns.

Note that 

  f(x) =              5x - 6 
-g(x) = -( x2 - 5x + 6)
----    ------------

simplifies to

  f(x) =                5x - 6 
-g(x) = - x^2  + 5x - 6
----    -------------

Please finish the combining.
