Answer:
f(- 2) = - 9.2
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 3.6(- 2) - 2 = - 7.2 - 2 = - 9.2
The y intercept is 4, and the x intercept is 0.
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.
