Question

Help? I need to find the domain, range, x and y intercepts, and the horizontal and vertical asymptotes for both of these functions.

Answer 1

What are the functions?

Answer 2

\[1) \frac{ 2 }{ x^2-2x-3 }\]

Answer 3

\[2) \frac{ x^2+x-2 }{ x^2-3x-4}\]

Answer 4

domain all real numbers

Answer 5

Which one?

Answer 6

both

Answer 7

Really? The first one looks weird on my calculator.

Answer 8

nvmd, 1st one is not x=4 or x=-1

Answer 9

range is y<=8/25 and y>0

Answer 10

-8/25***

Answer 11

Wait, are you saying the first one is x=4 and x=-1, or it is not equal to x=4, an -1?

Answer 12

all real numbers except those 2

Answer 13

no x int and y int is -1/2

Answer 14

hor asym at +/_ infinity
vert asym at -1 and 4

Answer 15

haha i screwed that all up. i took the numerator of your first equation and denominator of your second

Answer 16

First equation- Domain is all real numbers except -1 and 3, range is y<=-1/2 and y>0, no x int, y int=-2/3, hor asymptotes at +/- infinity and vert at -1 and 3

Answer 17

Ah, that makes more sense. :)
