The curve is y = sqrt{x}.
Replace x in the curve with 1 and then with 4 to find your point.
y = sqrt{1}
y = 1
First point (1, 1).
y = sqrt{4}
y = 2
Second point (4, 2).
Take it from here.
You get a positive number because you can use the leave, change, change rule for the signs. After the rule it would be a minus + a positive. The answer will vary depend on the size of each number.
It is not a function because there can't be two of the same number on the x-axis.
Answer:
Step-by-step explanation:
First you distribute so two times 4Y is 6Y then you multiply the two in the five which gives you 2Y -5 equals 70
