Question

The graph below shows the change in temperature in Troy, NY.

Answer 1

Answer:

Average 3am - 9am: $\frac{5}{6}$

Average 9pm - 3am: $\frac{1}{2}$

Step-by-step explanation:

Average Rate of Change: $\frac{f(b)-f(a)}{b-a}$

Step 1: Define coordinates

3am - 9am; (3, -3) and (9, 2)

9pm - 3am; (9, 0) and (3, -3)

Step 2: Find rate of change

$\frac{2-(-3)}{9-3}=\frac{2+3}{6} =\frac{5}{6}$

$\frac{-3-0}{3-9}=\frac{-3}{-6} =\frac{1}{2}$
