The statement (A) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches infinity is correct.
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have a polynomial function:

The function is a cubic function and the graph of the cubic function will be a curve.
As we can see in the graph, f(x) grows larger as x approaches negative infinity. f(x) also becomes closer to infinity as x does.
Thus, the statement (A) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches infinity is correct.

Answer:
85
Step-by-step explanation:
180 - (18+77)
3/4 = 21/28 after multiplying top and bottom of 3/4 by the value 7
3*7 = 21 and 4*7 = 28
The goal is to get 3/4 into an equivalent fraction that has 28 as the denominator.
------------------------------------
So 3/4 - 1/28 is the same as 21/28 - 1/28
The denominators are the same. We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28
We have
21/28 - 1/28 = (21-1)/28 = 20/28
Now reduce 20/28 as much as possible. Divide both parts by the GCF 4
20/4 = 5
28/4 = 7
The final answer is 5/7
