Which ordered pair is the vertex of y = |x + 2| – 1?

show me the steps

(1, –2)

(–1, 2)

(–2, –1)

(2, –1)

The vertex is the lowest or highest point

sub a massive positive value for x and we get a massive positiive value for y
sub a massive negative value for x and we get a massive positiive value for y
we need to find the minmum
make teh absolue value equal to 0

|x+2|=0
x+2=0
x=-2

at x=-2

sub to find y value
y=|-2+2|-1
y=|0|-1
y=-1

(x,y)
(-2,-1)

3rd option

Since the vertex of the parent function (original graph) is (0,0)
you move 2 units to the left because 'x+2' (if it was 'x-2' we move to the right, its a rule) and we move 1 unit down because '-1' again if it was +1 then vice versa. 
And that's your vertex (-2,-1)
Hope it Helped :)

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
