I believe it is d: whole numbers, integers, and rational numbers
The domain is the x-axis and the range is the y axis.
Example:
(-2,4) (6,7) (3,-8)
D:{-2,6,3}
R:{4,7,-8}
-6 is the answer because it is a even amount of negatives
b = 19
substitute x = - into the equation and solve for b
5(- )² - b + 12 = 0
+ = b
= b
multiply both sides by 5 and divide by 4
b = = 19
