first -shift left 3 units, reflect on the x-axis and stretch vertically by 10. (5,70)
second one- reflect across the y-axis, shift up 3 units (-8,-2)

anonymous · Answer

the 70 isnt correct...

anonymous · Answer

sorry its 50

anonymous · Answer

how did u get these numbers?

anonymous · Answer

you get them from the transformations, like shifting, and reflecting upon the x or the y-axis and also stretching the graph by multiplying by a factor. For example for (x+3) tou shift left 3 units, so your at (5,-5) and etc.

anonymous · Answer

what about the 50? how do u get that?

anonymous · Answer

multiplied the y value of 5 by 10.
