i tried, and failed

isnt x to any constant equal to dy/dx

is d/dx the same as dy/dx making it 4-3x - Mar 16th 2010, 07:25 PMdedust

**questions**, no work.

The first suggestion was that you use the "fundamental theorem of calculus". You said "I tried and failed". HOW did you try? What answer would the fundamental theorem give you? - Mar 17th 2010, 02:14 AM-DQ-
woudn't it just be (4-3x)(1) yielding 4-3x since it's going from a constant to x.

that is my work..
