A function is when you can look at any number on the graph, and it only has one value in the line. For example, look at 2 on the y-axis. It only has one point on the line, but -2 on the y-axis has two points on the line. I hope that makes sense.

Therefore the answer is B. No, because some of the y-values are paired with 2 x-values.

Hope this helps! :)

Answer:

DE ≈ 9.49, EF ≈ 8.06, FD ≈ 14.87
obtuse scalene triangle

Step-by-step explanation:

For finding side lengths, it is convenient to work with the differences of the coordinates.

DE = E(-1, -3) -D(8, -6) = (-9, 3)

EF = F(-2, 5) -E(-1, -3) = (-1, 8)

FD = D(8, -6) -F(-2, 5) = (10, -11)

Then the lengths are ...

DE = √((-9)² +3²) = √90 = 3√10 ≈ 9.49

EF = √((-1)² +8²) = √65 ≈ 8.06

FD = √(10² +(-11)²) = √221 ≈ 14.87

The lengths are all different and the largest angle is obviously more than 90°, so the triangle is an obtuse scalene triangle.
