Consider the Standard Normal distribution. The mean is always
What?
The standard deviation is always what?

The normal distribution is a symmetrical, bell-shaped distribution in which the mean, median and mode are all equal. It is a central component of inferential statistics. The standard normal distribution is a normal distribution represented in z scores. It always has a mean of zero and a standard deviation of one.

Step-by-step explanation:

the  x  coordinate of the vertex of  f(x)=|x+a|  is  xv=−a

a=2⇒xv=−2⇒yv=|−2+2|−1=−1
