Differentiate the function

∫(48x − 0.4x −1.4) dx

Ken,
 
The way the problem is stated, you ask for the derivative of an indefinite integral.  That will simply give you the integrand.  Is the problem worded correctly?  Also, as Michael pointed out, there may be a typo in the expression.  Please edit your question.

Ken,
 
If you are asking questions about differentiation, then why do your other questions have simple problems such as simplifying an algebraic expression and solving for an output with a known input?  You should be far above those questions.

You want to find the integral (anti-derivative).  Use the power rule.
 
First, rewrite the integral so that the coefficients are in rational form.
 
∫(48x - (2/5)x - (7/5)) dx
 
 
Formula for power rule is
 
∫Cxn = Cx(n + 1) / (n + 1)
 
 
Now you can integrate.  But, I think you need to revise this question.  Your integral as like terms in it.  I think one of these terms is a second degree term.
