To find the answers for the table, you must plug in each x value into the equation and get your y value:
x = -1
(-1^2)-(4*-1)-1
=
1+4-1
=
4
When x = -1, y = 4
x=0
(0^2)-(-4*0)-1
=
-1
When x = 0, y = -1
x = 1
(1^2)-(4-1)-1
=
1-4-1
=
-4
When x = 1, y = -4
x = 2
(2^2)-(4*2)-1
=
4-8-1
=
-5
When x = 2, y = -5
x = 3
(3^2)-(4*3)-1
=
9-12-1
=
-4
When x = 3, y = -4
I made a graph of this shown below.
I also created a table, that answrs your question below.
Hope this helps!

Step-by-step explanation:
Given that the owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club.
(Right tailed test)
Sample size =
Sample mean = 30.45
Mean difference =
Sample std dev s = 5
Sample std error =
Test statistic = Mean diff/std error =
Since population std deviation is not know we use t test
p value =
Answer:
The correct answer for this is .
Step-by-step explanation:
As it can be seen from the attached graph image:
- The <em>y-axis </em><em>increases in positive</em> values when we move in up direction i.e. we have +<em>y-axis </em>in upward direction.
- The <em>y-axis </em><em>decreases and keeps on becoming more and more negative</em> values when we move in down direction i.e. we have -<em>y-axis </em>in downward direction.
- The <em>x-axis </em><em>increases in positive</em> values when we move in right direction i.e. we have <em>+x-axis </em>in right direction.
- The x<em>-axis </em><em>decreases and keeps on becoming more and more negative</em> values when we move in left direction i.e. we have <em>-x-axis </em>in left direction.
Now, according to question, the translation is performed 6 points up i.e. towards positive y-axis and 4 points towards left i.e. towards negative x-axis.
And, as per rule, the co-ordinates are represented as where
is the x-co-ordinate and
is y-co-ordinate.
So, the answer here is .
