Wow, someone asked me this question and I'm stumped.
Find the equation of the secant line that contain [tex]P[0,f(0)][/tex] and [tex]Q[3,f(3)][/tex] Am I given enough information to solve this? [tex]m=\frac{f(x+h)f(x)}{h}[/tex] ... [tex]m_1=\frac{f(h)f(0)}{h}[/tex] [tex]m_2=\frac{f(3+h)f(3)}{h}[/tex] That doesn't really help me though, unless I'm not thinking hard enough!

Isn't a secant line just a straight line with those two points?
uhm.... [tex]m=\frac{f(3)f(0)}{30}[/tex] but the answer would be in terms of f(3) and f(0)

[tex]m=\frac{f(3)f(0)}{3}[/tex] [tex]yf(0)=\frac{f(3)f(0)}{3}(x0)[/tex] Not sure what else to think of.

I would hope that is all there is to it.
