Compare the function with the parent function. What are the vertex, axis of symmetry, and transformations of the given function? y = |10x-2| -7

is this the pre calc final?
Nope. Just a question from my algebra work that Im stuck on. Im in algebra 2
y = |10x-2|-7 = |10(x - 1/5)|-7
so, the graph has been shifted right 1/5, compressed horizontally by a factor of 1/10, and then shifted down 7.
Or, since you can also write it as
y = 10|x - 1/5|-7
you could say it has been stretched vertically by a factor of 10 and then down.

So what is the axis of symmetry and the vertex?
the axis of symmetry is where
x - 1/5 = 0 or in other words x = 1/5
Look, the absolute value sign means it is the same both right and left of here.
Now find y at x = 1/5 and you have your vertex
x - 1/5 = 0 or in other words x = 1/5
Look, the absolute value sign means it is the same both right and left of here.
Now find y at x = 1/5 and you have your vertex
(1/5,-7); x=1/5; translated to the right 1/5 unit and down 7 units.
It wouldn’t be up 7 units because the 7 is negative so therefore you’re going down

I need help same question different problem y=6x-2-7
Ashley I hope you’re right
