Answer:
The sum of all real numbers x that are not in the domain of the function f(x) is 2.
Step-by-step explanation:
The given function is
The domain is the set of inputs. So, the domain of the given function is all real numbers except those numbers for which denominator values is equal to 0.
It means is not included in domain.
It means 2 is not included in domain.
It means is not included in domain.
The sum of all real numbers x that are not in the domain of the function f(x) is
Therefore the sum of all real numbers x that are not in the domain of the function f(x) is 2.
Answer:
y = -0.25x + 40 ; $26,000
Step-by-step explanation:
From the graph attached ;
The regression equation, y could be obtained :
y = mx + c
m = slope = Rise / Run = (y2 - y1) / (x2 - x1)
Slope = (15 - 40) / (100 - 0)
Slope = - 25 / 100
Slope = - 0.25
c = intercept, where the regression line crosses the y-axis, from. The graph, c = 40
The regression equation goes thus :
y = -0.25x + 40 ; y = price of car ; x = number of miles driven
Price of car that has been driven for 56000 miles
y = - 0.25(56) + 40
y = - 14 + 40
y = 26
Hence, price of car is $26,000
