Answer:
A
Step-by-step explanation:
correct on edge
Since Steven ordered 500 hats, he cannot sell more than 500 hats, therefore, the domain of the profit function is {0 ≤ x ≤ 500}
Option D is the correct answer.
These are the statements that accompany this question:
<span>A.The function is a linear function.
B.The function is a nonlinear function.
C.The function does not change at a constant rate.
D.The function is an increasing function.
E.The function changes at a constant rate.
An this is the assesment of each of statement:
</span>
<span>A.The function is a linear function.
TRUE: a linear function can take the forms Ax + By - C = 0, or y = mb + b
You can verify that y = 2000 - 90 x is of this type.
B.The function is a nonlinear function.
FALSE: we showed the opposite in A)
C.The function does not change at a constant rate.
FALSE: the rate of change of a linear function is constant and it is known as the slope.
D.The function is an increasing function.
FALSE: the value of y decreases as x increases, given that the slope is negative ( -90).
E.The function changes at a constant rate.
TRUE: the constant rate is the slope, i.e. - 90.
