Question

?

Answer 1

start by factoring the numerator

Answer 2

um x-4

Answer 3

yup, so part I would be something like "x-4" can be cancelled out from the num and denominator

Answer 4

for part II just re-write G(x) after cancelling out (x-4)

Answer 5

g(x)=x^2-3

Answer 6

the original function is (x+1)(x-4)/(x-4)

cancelling out the (x-4) gives us (x+1) as our new G(x)

Answer 7

so would it equal like would it be g(x)=x+1

Answer 8

yes

part III is a removable discontinuity

for part IV graph H(x) (it will look like x + 1 but it will have an open circle at x = -4)

Answer 9

okay so what is the equation maybe i can go on demos and see the entire graph

Answer 10

it's just (x+1) with an open circle at x = -4

Answer 11

like that but with the right values

Answer 12

got it

Answer 13

*** should be an open circle at x = 4 not -4

anyway for the domain and range
the missing point is (4,3) so x takes on all real values except 4 and y takes on all values except 3
