also, draw on the graph.

i) The given function is

The factored form is

The domain are the values of  x for which the function is defined.

ii) To find the vertical asymptotes, equate the denominator to zero.

iii) To find the roots, equate the numerator to zero.

The root is

iv) To find the y-intercept, put into the function.

The y-intercept is

v) The horizontal asymptote is given by;

The horizontal asymptote is

vi) The function is not reducible. There are no holes.

vii) The given function is a proper rational function.

Proper rational functions do not have oblique asymptotes.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
