According to the definition of a function, since every element in the domain should be mapped to a single element in the codomain, the output of -2 should be either 2 or -1 but not both.
Note that the other elements in the domain have unique images.
So, to make the mapping a function, we need to remove (-2, 2) or (-2, -1).
Of these, (-2, -1) is only given in the options.
Hence, the ordered pair to be removed is (-2, -1).
Assuming that 6.8 means the area of the triangle, the height would be 1.94.
