The point-slope form: 
m = 3; (-1; 5)
subtitute
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
m = 3; (-1; 5)
subtitute
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1)
For this case we have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)

Answer:
Step-by-step explanation:
We are given the following in the question:
Significance level = 0.01
Width of interval = 0.1
Population variance =
We have to find the sample size so that the width of the confidence interval is no larger than 0.1
Formula for sample size:
where E is the margin of error. Since the confidence interval width is 0.1,
Putting these values in the equation:
So, the above expression helps us to calculate the sample size so that the width of the confidence interval is no larger than 0.1 for different sample variances.
