Answer:
(a)
(b)
Step-by-step explanation:
(a) can also be written as x
the = ± y
Therefore :
= ±
since it was given that y < 0 , then the factor will be
(b) can also be written as : x
Therefore , one of the factor is
A perpendicular line has a slope of infinity. Therefore it is not possible to write the equation in point-slope form.
The equation is x = -4.
We can explicitly find the inverse. If is the inverse of , then
Solve for the inverse :
Then when x = -6, we have
Alternatively, we can first solve for x such that . Then taking the inverse of both sides, . (The difference in this method is that we don't compute the inverse for all x.)
We have
