Hence, by comparing the general form, we would not be able to find any 'commonality'. <br /><br />Hm... may want to explore what happens to the parabola when "a" becomes extremely small...<br /><br />Let's see if anyone wants to make that attempt :)Loh Kwai Yinhttp://www.blogger.com/profile/09629206529240771085noreply@blogger.comtag:blogger.com,1999:blog-1417696443440891776.post-10801907361110066692010-10-02T12:28:40.730+08:002010-10-02T12:28:40.730+08:00No, a parabola has no gradient.

Reason 2: According to the equation given, "y = ax^2 + bx + c" is not equivalent to "y = mx + c", as the first equation does not have an "m" whereas the latter does. Since "m" represents the gradient, the first equation (parabola) has no gradient.t.jianhuihttp://www.blogger.com/profile/06354172526273501498noreply@blogger.com
