Step-by-step explanation:

Graphs of Exponential Functions

The graph passes through the point (0,1)

The domain is all real numbers.

The range is y>0.

The graph is increasing.

The graph is asymptotic to the x-axis as x approaches negative infinity.

The graph increases without bound as x approaches positive infinity.

Marizza181 [45]

Answer:

Method 1 has bigger forecast bias.

Step-by-step explanation:

We are given the following information in the question:

Actuals:

23, 10, 15, 19

Method 1 prediction:

23, 5, 14, 20

Residuals = Predicted - Actuals

Sum of square of errors:

$=(23-23)^2+(5-10)^2+(14-15)^2+(20-19)^2\\= 27$

Mean squared error:

$\dfrac{\text{Sum of squares}}{n} = \dfrac{27}{4} = 6.75$

Method 2 prediction:

20, 13, 14, 20

Residuals = Predicted - Actuals

Sum of square of errors:

$=(20-23)^2+(13-10)^2+(14-15)^2+(20-19)^2\\= 20$

Mean squared error:

$\dfrac{\text{Sum of squares}}{n} = \dfrac{20}{4} = 5$

Since, mean square error of method 2 is less as compared to method 1, method 1 has bigger forecast bias.
