<em><u>Explanation</u></em>:

One reason expanded form is important is because people need a basic understanding of what numbers mean. Expanded form of a number breaks it down into the value of each digit by place value, which shows us what the entire number means.

Another reason expanded form is important is because it can be used in mental math, making it quicker for us to answer questions.

Which inequality statement best represents the graph?
I am Lyosha [343]

Answer:

f(x) < –x2 + x – 1

Step-by-step explanation:

The graph is going down so we know that there is a maximum, therefore the A value has to be negative. This rules out f(x) < x2 + x – 1 and f(x) > x2 + x – 1 . The shaded area of the graph is below which indicates that f(x) has to be less than the function. This means the correct answer is f(x) < –x2 + x – 1 .
