{(-2, 6), (-5, -1), (3, 7), (-5, 0)}
Domain: The domain is all the x-values (-2, -5, 3, -5)
Range: The range is all the y-values (6, -1, 7, 0)
Function: It's not a function because of the x-value -5 is repeating.
Answer:
Step-by-step explanation:
domain (ur x values) = [ -5,-2,3 ]...only write repeating values once
range (ur y values) = [ -1,0,6,7]
a function will not have any repeating x values....it can have repeating y values, just not the x ones...all x's have to be different
therefore, this is not a function because u have repeating x values of -5
the answer is A
0.15x + 30 ≤ 100
0.15x ≤ 70
1 hour
Because 3 - 2 = 1.
Therefore, 1 hour only.
X-16 the first one
The first one is equal to x-4
