Answer:
A. f(x) = -|x|
Step-by-step explanation:
just did it
You circle the points on both sides and then you calculate them and get what you need...
Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
5x(4x^3 + 3x - 2)
There’s a 5 and a x common.
