For this case, the first thing we must do is take into account the definition of the axes:
 the x axis is time in seconds
 the y axis is velocity in meters per secon
 
 Then, we look for the cut point with the y axis, which is given by:
 (0, 2)
 This means that the initial speed is 2 m / s.
 
 We now look for the cut point with the x axis, which is given by:
 (8, 0)
 This means that the speed is 0 m / s, so the runner stopped when the time is 8 seconds.

 Answer:
 
The initial velocity of the runner was 2 m / s, and the runner stopped after 8 seconds.

Calculate the average rate of change for the given function, from x = −3 to x = 7.
emmainna [20.7K]

Answer:

The average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5

Step-by-step explanation:

Given the table

x                      f(x)

-3                     50

3                      10

7                       0

As the interval is from x = -3 to x = 7.

so

at x₁ = -3, f(x₁) = 50

at x₂ = 7,  f(x₂) = 0

Using the formula to determine the average rate of change at which the total cost increases will be:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                       = [0 - 50] / [7-(-3)]

                      = [-50] / [7+3]

                      = -50 / 10

                      = -5

Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5

Let f(x) = 3x +2 and g(x) = 7x + 6. Find f • g and its domain.
Alekssandra [29.7K]
The value of f·g is the product of f(x) and g(x). This is shown below,
                                 f·g = (3x + 2)(7x +6)
                                 f·g = 21x² + 32x + 12
The domain of the function is the value of x that would make the function reasonable. The domain is all real numbers.
