Question

Please help on this one?

Answer 1

Answer:

C

Step-by-step explanation:

The rate of change is measured using

$\frac{f(b)-f(a)}{b-a}$ in the closed interval [a, b ]

Here [a, b ] = [35, 45 ]

from the table f(b) = f(45) = 34.1 and f(a) = f(35) = 31.4, hence

rate of change = $\frac{34.1-31.4}{45-35}$ = $\frac{2.7}{10}$ = 0.27 → C
