Step-by-step explanation:
x y
1 2
2 4
3 9
4 16
This sounds like a quadratic equation of f(x)=x^2, thus, the range is:
<h3>
R(x): (-∞,+∞)</h3><h3 /><h3>
If the function only has these points, then the range is:</h3><h3>
R(x): [2]∪[4]∪[9]∪[16]</h3>
Answer:

Step-by-step explanation:
Step-by-step explanation:
<h3>Vocabulary (what the words mean):</h3>
Divide, the same as ÷
divide 6 <u>by</u> 3
<u>by</u> is the same as the symbol
6 ÷ 3 = 2
Difference, This is another way of saying take away or minus
the difference of 6 and 3 is
6 - 3 = 3
Product, This is another word for multiply or times
the product of 2 and 3 is
2 × 3 = 6
<h3>Write as an equation</h3>
divide <em>(÷)</em> the difference of 20 and 6 <em>(20 - 6)</em> <u>by</u> the product of 7 and 2 <em>(7 × 2)</em>
<em />
<em>so </em>
<em>(20 - 6) ÷ (7 × 2)</em>
<em />
<em>can you do the rest???</em>
Answer:
B. y = 
Step-by-step explanation:
I. Given x = 15 and y = 4
4 = 
4 = 2+2
4 = 4 true
II. Give x = 0 and y = 2
2 = 
2 = 0 + 2
2 = 2 true
III. Given x = -15 and y = 0
0 = 
0 = -2 + 2
0 = 0 true
Good luck.
