an equation is undefined, when its denominator is 0, or turns to 0, because we can't divide anything by 0.
so let's simply set the denominator of this one = 0.
The domain and range of a function is the set of input and output values, the function can take.
- <em>The domain is [0,6]</em>
- <em>The range is [0,90]</em>
<em />
From the question, we have:
<u>The domain</u>
He cannot mow more than 6 yards a day.
This means that the domain is: 0 to 6
<em>This is properly represented as: [0,6]</em>
<u></u>
<u>The range</u>
When he mows 0 yards, his earnings is:
When he mows 6 yards, his earnings is:
This means that the range is: 0 to 90
<em>This is properly represented as: [0,90]</em>

Answer:
5. 49, (x+7)²
6. 36, (x-6)²
7. 81/4, [x-(9/2)]²
Step-by-step explanation:
5. x² + 2(x)(7) + 7² = (x + 7)²
6. x² - 2(x)(6) + 6² = (x - 6)²
7. x² - 2(x)(9/2) + (9/2)² = (x - 9/2)²
For these similar figures we can write, ratios of their corresponding sides
GH/EA = JI/EA, because GH=JI
JI/EA = y/HI
9/20.25 = y/5
y=9*5/20.25≈ 2.2
