How to know when there is a vertical dilation or a horizontal dilation?

Given a function and a number , if you multiply the whole function by , you have a vertical dilation:

If , you follow the same steps as before, but you also reflect the function around the x-axis.

If, instead, you multiply only the argument by , you have a horizontal dilation:

If , you follow the same steps as before, but you also reflect the function around the y-axis.

answer: ok

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.
