Step-by-step explanation:
A drop in temperature is indicated by - ( negative symbol )
A drop of 2° followed by a drop of 3° is
- 2 + (- 3) = - 2 - 3 = - 5°
the sign of the sum is - ( negative add a negative is negative )
the total change in temperature is - 5°
the sum of 2 positive integers is positive , that is
+ 2 + (+ 3) = + 2 + 3 = = + 5
Let [a, b] = the interval
The average rate of change can be found by using [f(b) - f(a)]/(b - a).
Let a = 1 and b = 5.
Let R = rate of change
17- x^2
R = [17 - 5^2] - [17 - 1^2]/(5 - 1)
R = [17 - 25] -[17 - 1]/4
R = [(-8) - (16)]/4
R = (-24)/4
R = -6
Done.
