Answer:
to complete the square, you add (b/2)^2 on both side. in this case, b is -6, half of -6 is -3, -3 squared is 9, so:
x^2-6x+9=-13+9
(x-3)^2=-4
This quadratic equation have unreal solutions
Step-by-step explanation:
The y-intercept of the line would change but the slope would not.
Slope is the rate of change of a line. If the y-values all decrease the same amount, the rate that the line is changing will not change. For example, let's take the points (5, 6) and (3, 2). The slope is given by (6-2)/(5-3) = 4/2 = 2. Now let's decrease the y-coordinates all by 2:
(5, 4) and (3, 0)
The slope now would be (4-0)/(5-3) = 4/2 = 2.
By changing the y-values the same amount, the amount of difference between them stays the same, and so does the rate of change of the line.
Since we shifted the y-values down, however, this moves the line down on the graph, which will change the y-intercept.

Answer:
a) find the attached graph
b) find the attachment no 4 and 5
c)
Step-by-step explanation:
a) A trend pattern exist if the time series plot gradually shifts to higher or lower values over a long period of time
find the attached graph
b) Liner Trend Equation
Where 
is the linear trend forecast in period t , 
is the intercept of the linear trend time, 
is the slope of the linear trend line, t is the time period
now computing the slope and intercept
<u>formula is attached ( 3 no attachment)</u>
is the value of the time series in period t, n is the number of time periods
Y(bar) is the average value and t(bar) is the average value of t
<u><em>due to unavailability of equation in math-script i attached the calculation part of this question( 4th and 5th no attachment)</em></u>
thus the linear trend equation is 
(1)
