80% = 0.8
100% = 1
0.8 = 72
1 = x
0.8* x = 72 * 1
x = 72 / 0.8 = 90
0.8 * 90 = 72
80% * 90 = 72
b-(-2,-1)
c-(1,-3)
d-(3,7)
Answer:
b - (-2,-1)
Step-by-step explanation:
A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.
In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1). If one of these two was removed, the mapping becomes a function.
The only one of these listed in the values given is (-2, -1).
Answer:
(-2,-1)
