Step-by-step explanation:
the answer is in the image
5.6-4.9=x
.7= x is the answer not .8
the formula for a horizontal shift is (x-a) and this graph has moved 2 units to the left, -2, so the formula becomes (x+2)
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.
