How do you solve f(x)=square root of 2x+1 using the difference quotient? I need to see the steps.

  • college algebra - ,

    what do you mean by "solve"?
    f(x) = √(2x+1)
    doesn't involve a difference quotient.

    If you want to write down the difference quotient, then that would be

    (f(x+h)-f(x))/h
    = (√(2(x+h)+1) - √(2x+1))/h
    = (√(2x+1+2h) - √(2x+1))/h

    Not sure where you want to go with that . . .
