Calculus Michael Spivak 3th ed. Pag 46: Function as a rule

    He begins to do a rethink about what is a function.
    Function is a rule? If it is a rule then:
    f(x) = x²
    and
    f(x) = x² +3x + 3 -3(x+1)
    are different. But that was not what we wanted.

    But he rewrites, this way:
    f(x) = x²
    and
    f(x) = x² +3x +3 -c(x+1)

    Apparently this was a small mistake.

    I would like to hear the opinion of colleagues. Thank you.

    Looks like a typo yes. Every book has a few, you should just correct it as you did and carry on.

    I have the first edition, which doesn't have the typo. Sometimes books get worse instead of better when new editions are published. :frown:
