Answer:
d) (3, 4), (5, 5), (5, 2)
Step-by-step explanation:
<em></em>
<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>
Using the definition of range:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
B² = 8b + 84
b² - 8b - 84 = 0
b = <u>-(-8) +/- √((8)² - 4(1)(-84))</u>
2(1)<u>
</u>b = <u>8 +/- √(64 + 336)</u>
2
b = <u>8 +/- √(400)
</u> 2<u>
</u>b = <u>8 +/- 20
</u> 2
b = 4 <u>+</u> 10
b = 4 + 10 b = 4 - 10
b = 14 b = -6
