What is the equation of a parabola that intersects the x-axis at points (-1, 0) and (3, 0)?

A. y = x2 – 2x – 3

B. y = x2 + 3x + 2

C. y = x2 – 3x + 2

D. y = x2 + 2x – 3

Step-by-step explanation:

The given points are zero's or roots of the function.

We can put the equation as:

This is option A

a

Step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
