(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

My cubic function is y=(x-6)(x-1)(x-9) or y=x^3-16x^2+69x-54

I need to find the tangent at the point x=2.5

2. Relevant equations

3. The attempt at a solution

All that I have managed to do is work out the y value for x=2.5, that is y=34.125

Please help someone!
