Answer:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.
Step-by-step explanation:
We are given the function f(x) = - |x| +4. We know that the function f(x) = |x| only has positive values, so when x>0 the function is a straight line as in the function f(x) = x. When x<0 the function is also positive, as in the function f(x) = -x. So the graph is V-shaped with the vertex at the origin.
The f(x) = - |x| +4 has two important caracteristics:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.
So the graph of f(x) = - |x| +4 will be V-shaped, reflected in the x-axis and moved 4 units upwards.

Answer:
the line of best fit is almost linear
the type of correlation is strongly positive
the slope is approximately 1/1
the y-intercept is -11/5
equation: y = 27/25x - 11/5

Answer:
-157.87
Step-by-step explanation:
1) the rules are:
and
![log_ab^c=c*log_ab.](https://tex.z-dn.net/?f=log_ab%5Ec%3Dc%2Alog_ab.)
2) according to the rules above:
![log_7(yz^8)=log_7y+8log_7z=-6.19-8*18.96=-157.87.](https://tex.z-dn.net/?f=log_7%28yz%5E8%29%3Dlog_7y%2B8log_7z%3D-6.19-8%2A18.96%3D-157.87.)
0,5 but ye don’t quote me on this one but I have a strong feeling that what it is
2(-3)-(-3)(4) = -6-(-12) = -6+12 = 6
