Answer 16

give me a sec to try and solve it, i do it on paper

Answer 17

ok

Answer 18

how's it going?

Answer 19

Good

Answer 20

A) c(x) = x^2+4x-5/(x+5) would be undefined at x = -5 because the denominator = 0 (zero) , which means it is undefined.

Answer 21

so for a) identify the restricted domain you say "all real numbers except \(-5\)"

Answer 22

seems right @satellite73 ?

Answer 24

yes it is right

Answer 25

thank you

Answer 26

then factor and cancel

Answer 27

ok next

Answer 28

next is part B
factor the numerator, then cancel the common factor of \(x+5\)

Answer 29

Now let's simplify c(x). The numerator factors to (x+5)(x-1)
c(x) = x^2+4x-5/(x+5) = (x+5)(x-1)/(x+5) = x-1

Answer 30

right?

Answer 31

yes right
you end up with only \(x-1\)

Answer 33

and for c) just graph it: The graph of x-1 is a straight line with a slope of 1 and y-intercept of -1. Place a small circle on the line at x=-5 to indicate that no value is defined for c(x) at this point.

Answer 34

yup
then graph the line \(y=x-1\) except put a whole where \((-5,-6)\) should be

Answer 35

hole* ;)

Answer 37

juicey?

Answer 38

you need to graph the line dear

Answer 39

??????

Answer 40

mhmm

Answer 41

plot some points, connect the dots
say \((0,-1)\), \((2,1)\) and \((4,3)\)
ought to be enough
you just put a dot down, you need a line

lol

Answer 51

ok fine
vertical asymptote set the denominator equal to zero solve for x (in your head)
what do you get ?
