Didnt u already get the answer i’m very confused rn
Answer:
for the domain, find the point on the farthest side (the left) and the closest (the right)
so for yours it would be [-3,2]
it's brackets because the points are closed.
for the range, same thing but for the y intercept.
so it's [-2,4]
there's your answer!
Answer: B - 24 Degrees
Step-by-step explanation:
3x+12 = 6x
12 = 3x
4 = x
[3(4)+12] = 24
6(4) = 24
I assume you mean one that is not rational, such as √2. In such a case, you make a reasonable estimate of it's position, and then label the point that you plot.
For example, you know that √2 is greater than 1 and less than 2, so put the point at about 1½ (actual value is about 1.4142).
For √3, you know the answer is still less than 4, but greater than √2. If both of those points are required to be plotted just make sure you put it in proper relation, otherwise about 1¾ is plenty good (actual value is about 1.7321).
If you are going to get into larger numbers, it's not a bad idea to just learn a few roots. Certainly 2, 3, and 5 (2.2361) and 10 (3.1623) shouldn't be too hard.
Then for a number like 20, which you can quickly workout is √4•√5 or 2√5, you could easily guess about 4½ (4.4721).
They're usually not really interested in your graphing skills on this sort of exercise. They just want you to demonstrate that you have a grasp of the magnitude of irrational numbers.
