Answer:
D=(-infinity, +infinity)
R=(-infinity, 4]
Step-by-step explanation:
I think that 2 is an exponent so you function is f(x)=-3(x-5)^2+4
So if this is the case this is a parabola open down when a vertex of (5,4).
Visualize or draw a rough picture of that because that is all you need to answer this question.
The domain for a parabola function is always all real numbers (do notice I said parabola function).
The range for this parabola is (-infinity, 4] since open down and the highest point has y value 4.
This equation would not be correct.
In the left expression, cscAsecA contains the variable 'e' which is not present in the second expression.
Answer:
Business A= x
Business B= 2x-2,000,000
Business C= 2(2x-2,000,000)-2,000,000
Step-by-step explanation:
Don't feel like explaining this unless you really want me to. Also, brainliest would really be appreciated.
The dealer paid 'C' for it. He decided to sell it for 10% more than C .
That would be (1.10 C) , and that's the $856.90 .
So the equation is . . . 1.10 C = $856.90
Divide each side by 1.10 : C = $856.90 / 1.10
<em>C = $779</em>
