Answer:
(a) Is not possible
(b) It is possible
(c) It is possible
(d) Is NOT possible.
Step-by-step explanation:
(a)
Is not possible, notice that for any function 
such that
you would have that
And for, lets say -3,3 you have that
therefore is not possible to find a function that is one to one.
(b)
It is possible. Take the following function
since 
is periodic it will take positive and negative numbers and if you multiply by 
each period will become bigger and bigger.
(c)
It is possible. Take the function
Then
and 
is one to one.
(d)
It is NOT possible because 
and that will always be positive.

Answer:
a = 138
Step-by-step explanation:
Notice that from the figure, we can see that ∠MOQ and ∠PON are vertical angles, which means that by definition, they're congruent in measure.
∠MOQ = ∠MOR + ∠ROQ = 90 + 48 = 138°
So, this means that ∠PON is also equal to 138, which means a = 138.
Thus, the answer is a = 138.

Answer:
x- intercept = 8 , y- intercept = - 2
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x
x - 4(0) = 8
x - 0 = x
x = 8 ← x- intercept
To find the y- intercept, let x = 0 in the equation and solve for y
0 - 4y = 8
- 4y = 8 ( divide both sides by - 4 )
y = - 2 ← y- intercept
