Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above

<em>Correct Presentation of Question</em>
<em>Which numbers are domain? (-3,-2) (3,0)(-1,2)(1,2)</em>
Answer:
Domain = {-3,-3,-1,1}
Step-by-step explanation:
Given
(-3,-2) (3,0)(-1,2)(1,2)
Required
Determine which numbers are domain
A function is always represented as thus (x,y) in this format (domain, range);
Tabulate the given data
x || y
-3 || -2
3 || 0
-1 || 2
1 || 2
The values under the x column are the domain;
Hence, the domain are {-3,-3,-1,1}
Answer:
Slope = m = First difference.
Step-by-step explanation:
The first difference of a function y = f(x) at any point (h,k) represents the slope of the tangent drawn at that point on the curve y = f(x).
If it is a linear function with equation say, y = mx + c, which is in slope-intercept form and the constant m is called the slope of the equation and it is nothing but the tangent function of the angle that the straight makes with the positive x-axis.
Now, the first difference of y with respect to x i.e. 
{Differentiating the equation y = mx + c with respect to x both sides}
So, slope = m = first difference. (Answer)
