Answer:
Option D
Step-by-step explanation:
Set of data in terms of ordered pairs represents a function when output value of each input value is different.
Option A
Since, for every value of x there is a different value of y, it's a function.
Option B
In each ordered pair, for every value of x there is a different value of y.
Therefore, it's a function.
Option C
From the given graph, for every value of x there is a different value of y.
Therefore, it's a function.
Option D
From the given set of ordered pairs we find for x = 1 there are two values of y (y = 4 and 3).
Therefore, the given set of ordered pairs doesn't represent a function.
Option D is the answer.
Let p be the pre-tax cost. Then 1.08p = $50. Solving for p, the pre-tax cost, we get:
p = ($50) / (1.08) = $46.30.
The answer is 28

Answer:
D . f(x) =2x²+3x-3
Step-by-step explanation:
Given the equation as
f(x)=2x²+3x-3
The leading coefficient is in the term with the highest power , x², which is 2
The constant term is -3
