If [tex]f(x)=x^3-6x+c_2[/tex] and I know that [tex]y=5-3x[/tex] is tangent at the point where x=1,
then I can say that at x=1 [tex]f(x)=x^3-6x+c_2|_{x=1}=5-3x.[/tex]
Right? and then I can solve for [tex]c_2[/tex]
I am getting the correct answer to my text problem, but I want to be sure that it is because my reasoning is correct.
