Answer:
Please check the attached graph.
From the graph, it is clear that option B is the correct option.
Step-by-step explanation:
Given the function
Determining the y-intercept
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
so
substituting x = 0 in the fuction
Apply rule:
Therefore, the point representing the y-intercept is:
- (0, 1.5)
Determining the x-intercept
We know that the value of the x-intercept can be determined by setting y = 0, and determining the corresponding value of x.
so
substituting y = 0 in the function
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
We know that can not be zero or negative for x ∈ R
Thus, NONE represents the x-intercept.
Please check the attached graph.
From the graph, it is clear that option B is the correct option.
QUESTION 1
If a function is continuous at , then
Let us find the limit first,
As ,
,
and
Let us now find the functional value at
Since
, the function is continuous at
.
QUESTION 2
The correct answer is table 2. See attachment.
In this table the values of x approaches zero from both sides.
This can help us determine if the one sided limits are approaching the same value.
As we are getting closer and closer to zero from both sides, the function is approaching 2.
The values are also very close to zero unlike those in table 4.
The correct answer is B
QUESTION 3
We want to evaluate;
using the properties of limits.
A direct evaluation gives .
This indeterminate form suggests that, we simplify the function first.
We factor to obtain,
We cancel common factors to get,
The correct answer is D
QUESTION 4
We can see from the table that as x approaches from both sides, the function approaches
Hence the limit is .
See attachment
The correct answer is option A
