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.
When rounding to the nearest hundred, if the number in the tens place is less than 5, you should round downwards (keep the same number shown in the hundreds place). However, if the number in the tens place is 5 or greater, than you have to round up, which means adding one to the number currently in the hundreds place.
So, for this problem, the digit 1 is in the tens place. Because 1 is less than 5, we know that we have to round down.
Thus, 218 rounded to the nearest hundred is 200.
Hope this helps!!

Answer:
All real numbers would be the solution
Step-by-step explanation:
2y - 4x =2 and y = 2x + 1
We solve but placing the value of y into the first equation:
2(2x + 1) - 4x = 2
Next we distribute the 2 through the parenthesis:
4x + 2 - 4x = 2
Now we gather like terms:
2 = 2 ( note the 4x and - 4x cancel out)
Since 2 =2 this tells us that all real numbers would work.
