Answer:
C
Step-by-step explanation:
The rate of change is measured using
[tex]\frac{f(b)-f(a)}{b-a}[/tex] 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 = [tex]\frac{34.1-31.4}{45-35}[/tex] = [tex]\frac{2.7}{10}[/tex] = 0.27 → C
