Answer:

2, 6, 11

Step-by-step explanation:

To evaluate f(- 1) substitute x = - 1 into f(x)

f(- 1) = 2(- 1)³ - 3(- 1)² + 7 = 2(- 1) - 3(1) + 7 = - 2 - 3 + 7 = 2

Similarly

f(1) = 2(1)³ - 3(1)² + 7 = 2(1) - 3(1) + 7 = 2 - 3 + 7 = 6

f(2) = 2(2)³ - 3(2)² + 7 = 2(8) - 3(4) + 7 = 16 - 12 + 7 = 11

The graph below shows the distance in miles, m, hiked from a camp in h hours.
Artist 52 [7]

Answer:

Option 1) is correct

Step-by-step explanation:

Given: The graph shows the distance in miles, m, hiked from a camp in h hours.

To find: hourly interval that had the greatest rate of change

Solution:

Rate of change between two points refers to the vertical change divided by the horizontal change.

For hour 0 to hour 1:

rate of change = \frac{2-0}{1-0}=2

For hour 2 to hour 3:

rate of change = \frac{4.5-3.5}{3-2}=1

For hour 1 to hour 2:

rate of change = \frac{3.5-2}{2-1}=1.5

For hour 3 to hour 4:

rate of change = \frac{5-4.5}{4-3}=0.5

So, rate of change is greatest in interval: hour 0 to hour 1

erastovalidia [21]
Check all the ones listed below:

1. The base is 3

(you are multiplying 3 four times or 3 to the power of 4 )

2. The exponent is 4

( 3 is the number you are multiplying and the exponent or 4 tells you how many times you multiply the base which is 3)

3. The exponent tells you to multiply the 3 together 4 times

( 3x3x3x3 is multiplying the number 3, 4 times)
