Hello all,
Just reviewing for the finals and stumbled upon some questions I'm having issues with. Conics mostly (I literally failed that chapter way back when).
1) "Find the focus of the graph y = 1/8(x-2)+3
2) "Find the sum of the series: -1 + 2 + 5 + 8... +56" (for this one, I resulted with S(19.3333) = 531.6657. Which is not one of the multiple choice answers).
3) "f(x) = x-4 and g(x) = x^2, find g(f(3))"
4) "Find the foci of the ellipse x^2+9y^2=81"
5) "Find the verticle asymptotes f(x) = x-1/x^2-25"
Thanks in advance!
