ANSWER CHECK Am I right if not pls tell me the right one pls

Yes you are right, the function that we get from the examples fits -1 with 2.

-1

Step-by-step explanation:

You are correct. If you look on the chart, -1 in the y - axis right next to 2 in the x-axis. When you look at the table 0 is right by the 3 and 1 is right by the one but when you look at the last two numbers on the chart which are -1 and 2 those numbers are right next to each other. The question asks you, using the table, what is the value for the range when the domain is 2? When looking at the chart you can easily tell what the value is for the range, it´s -1.  The y- axis and the x-axis are listed with numbers across from each other. For instance 0 (x-axis) and 3 (y-axis are right accross from each other, 1 (x) and 1 (y) are right across from each other and 2 (x) -1 (y) are right across from each other. So when you look at the last 2 number of the x and y - axis you can automatically see that -1 is the range of 2

I don't know what kind of triangle it is, but I have a formula for a right triangle. The formula is A= ab/2 The A Is one of the sides (Not the hypotenuse) and B Is the other (Not the hypotenuse) After you multiply those two numbers; you will have to divide them by 2. i hope this helped ^^
