Answer: B. Domain: All Real Numbers Range: y > -4
Answer: A. Stretched by 2, right 3, and up one
Step-by-step explanation:
We know this because the y value starts at -4 and only goes up, so y is greater than -4. We know the domain is all the real numbers because as you can see, the x value comes in fro the left infinitely, and although the graph starts rising, the graph continually goes right forever, too.
Step by Step (Question 2):
We can see it is multiplied by 2, therefore stretched, and we see the exponent says -3, but this exponent is known as a lying exponent and it is the opposite so it is +3, making it go right 3, and we see it is +1, which makes it go up 1.
