Answer:
Domain is (8,7,6,5) and Range is (7,7,7,7)
3(x + 1) + 6 = 33
3(x + 1) = 33 - 6 = 27
x + 1 = 27/3 = 9
x = 9 - 1 = 8
x = 8
ANSWER TO QUESTION 1
.
EXPLANATION
The function given to us is,
According to rational roots theorem,
are possible rational zeros of
.
We find out that,
Also
This implies that
are factors of
and hence 
is also a factor.
We perform the long division as shown in the diagram.
Hence,
.
ANSWER TO QUESTION 2
Sketching the graph
We can see from the factorization that the roots
and 
have a multiplicity of 1, which is odd. This means that the graph crosses the x-axis at this intercepts.
Also the root 
has a multiplicity of 2, which is even. This means the graph does not cross the x-axis at this intercept.
Now we determine the position of the graph on the following intervals,
We can now use these information to sketch the function as shown in diagram
Answer:
the relation is not one-to-one.
Step-by-step explanation:
it can't because every number is in the 4th quadrant.
Answer:
3rd option
Step-by-step explanation:
The range are the values covered on the y- axis
The lowest value is - 2
The highest value is 6
Both points have a solid circle on them indicating y can equal those values
range { y : - 2 ≤ y ≤ 6 }
