<span>You have to apply the rule to the XYZ coordinates, so
X'= (-2-1, 1+3)
Y'= (-4-1, -3+3)
Z'= (0-1, -2+3)
So the new coordinates are X' (-3, 4), Y' (-5, 0), and Z'(-1, 1)
This is actually translation not transformation, as the shape doesn't change it just moves</span>
The mean is 35/5=7
The variance is the average of the sum of squared differences of each element from the mean:
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
f = 2
Simplify both sides of the equation <span><span>1.25f</span>+2</span>=<span><span>−<span>2.75f</span></span>+<span>10
Add 2.75 to each side </span></span><span><span>4f</span>+2</span>=<span>10
Subtract 2 from both sides </span><span>4f</span>=<span>8
Divide each side by 4 </span>f=<span>2</span>

F(3) is 3 since the equation of the line is f(x)=3
They can show the rising and decreasing functions of the data.
