Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)
7 > z + 18 ≥ 6
Subtract 18 from all 3 parts:
7-18 > z +18 -18 ≥ 6-18
-11 > z ≥ -12

Answer:
Its the last option
y = 1488.33x + 23800 ; $172,600.
Step-by-step explanation:
The slope of the trend line = (median value for 2000 - median value for 1940) / 60
= 89300 / 60
= 1488.33.
So the equation is 1488.33x + 23,800
Estimate for 2040
is 1483.33* 100 + 23800
= 172,600.
285 liters is 75.289 U.S. gallons.
