Question 195457: Rewrite each function to make it easy to graph using a translation. Describe the graph.
[] means its in square root!! please help me
y=3[-27x-27]+4
y=[16x-32]
and can you tell me how many numbers did is shift right/left?? THANKS

y=3[-27x-27]+4
---
y = 3*sqrt(-27(x+1)) + 4
---
y = 3*3sqrt(-3(x+1)) + 4
---
y = 9*sqrt(-3(x+1)) + 4

The vertex is at (-1,4) ; the top half of the parabola opens to the left.
------------------------------------
y=[16x-32]
---
y = sqrt(16(x-2))
y = 4sqrt(x-2)
---
The shift is two to the right.
