**calculus**

I'm feeling pretty stupid right now because I can't remember how to do these. if f(x) = (2x-5)/(x^2-4), write an equation of the tangent line to f at point x=0. *How do I find the slope of the tangent line? and how do you put x=ln4 into a y= equation? Take the ...

**AP Biology- development and reproduction**

I'm trying to teach myself the rest of my AP bio book before the exam, and i don't get this stuff on development and reproduction. my teacher said she didn't know because she hasn't had to teach this stuff before, so any help would be great! 1. hows the dorsal ...

**AP Calc-easy ?**

Given: f(x)= x^3 + x^2 - 2x over the closed interval [0,2] Write the equation of the tangent line to f(x) passing through point A(-1,-2). *At first glance I knew how to do it, but f(-1) does not equal -2...so do I add a constant onto f(x) to make f(-1) = -2 or what? thanks
