A-domain: positive integers; range: positive integers; No, it is not a function.
Nookie1986 [14]

Answer: y>0

Step-by-step explanation:

Let's look at the graph. If we do the vertical line test, we can figure out that YES, it is a function, so option b and c are already out of the picture.

Now, to find the domain, look at the graph and shade it back to the x-axis. The domain includes every number greater than 3, so the domain is x>3.

To find the range, take a look at the graph and shade it back to the y-axis. The range includes every real number greater than 0, so the range is y>0

This means that d is the answer.

I really hope this helps!

Best wishes :)

Could someone please just help me out. i’m struggling pleasee
Aloiza [94]

Answer:

NO = 4.5

MO = 3.5

LN = sqrt(44)

Step-by-step explanation:

Since the value of the base of the triangles is 8, and the value of NO is 4.5, the value of MO is MN - NO, which is 8 - 4.5, which comes out to 3.5.

Then, we apply the quadratic formula to triangle MLO to find that the middle line value is sqrt(23.75). Then we use the quadratic formula on traingle OLN to find the LN is sqrt(44).
