Answer:
The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) =
Step-by-step explanation:
The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.

The parts of the product are the <em>multiplicand</em> and the <em>multiplier</em>. Those parts are also called <em>factors</em>.
Answer:
The first three, (2, 8), (3, 9) and (4, 10).
Step-by-step explanation:
The unit rate, or rate of change, is another term for the slope.
The formula for slope is
.
The slope in the table would be given by
m = (22-11)/(10-5) = 11/5 = 2.2.
For the slope of the line that goes through (2, 8) and (0, 0), we have
m = (8-0)/(2-0) = 8/2 = 4. This is greater than 2.2.
For the slope of the line that goes through (3, 9) and (0, 0), we have
m = (9-0)/(3-0) = 9/3 = 3. This is greater than 2.2.
For the slope of the line that goes through (4, 10) and (0, 0), we have
m = (10-0)/(4-0)/ = 10/4 = 2.5. This is greater than 2.2.
For the slope of the line that goes through (5, 8) and (0, 0), we have
m = (8-0)/(5-0) = 8/5 = 1.6. This is not greater than 2.2.
For the slope of the line that goes through (6, 7) and (0, 0), we have
m = (7-0)/(6-0) = 7/6 = 1.16. this is not greater than 2.2.
For the slope of the line that goes through (7, 6) and (0, 0), we have
m = (6-0)/(7-0) = 6/7 = 0.86. This is not greater than 2.2.
