Answer:
.
Step-by-step explanation:
In this question, (sales price) and (discount rate) are both given. The unknown is the regular price, .
Rearrange the discount equation to solve for in terms of and .
.
.
Divide both sides by :
.
.
It is given that . A mark-down of is equivalent to a discount rate of . Substitute in and to find the value of :
.
Thus, the regular price would be .
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).
