Answer:
-4 ≤ y ≤ 2 or [-4 , 2]
Step-by-step explanation:
The maximum of the function is +2 while the minimum is -4, the range is
-4 ≤ y ≤ 2 or [-4 , 2]
Answer:
50°F
Step-by-step explanation:
Given the equivalent celcius and Fahrenheit temperature relation :
t℃=(32+1.8t)℉
t = any rational number :
Taking a rational number, t = 10
The Fahrenheit temperature obtained will be :
t°C = 10
t℃=[32+1.8(10)] ℉
10°°C = (32 + 18)°F
The equivalent Fahrenheit temperature = 50°F
1/4 is 0.25 so it would be 3.25
We can model the function in that interval as a straight line of negative slope.
We have then that the average rate of change in that interval is given by:
r = (y2-y1) / (x2-x1)
Substituting values:
r = (- 4-4) / (2π-π)
Rewriting we have:
r = -8 / π
Answer:
the rate of change from x = π to x = 2π is:
r = -8 / π
