ok so i got few questions so i was given a equation like this

y= -1/4 | 2(x+1)|+9

i identify that the parent function is y = |x| , but i totally forgot how to input the number.. as in when u plug in x what do u get as y. Does it always remain positive for an aboslute value.

2.) so if u were given a equation like this y= -[ 1/2 (x+2)]^2+10 , the negative sign in the front, is represent as -1 = a , from the general formula. Or is it just a negative sign there, if so, do u not include the transformation of a in the graph?
