Question

PLEASE PLEASE PLEASEE PLEASEEEEESE HELPME!?!?!? IM SO BAD AT MATH PLEASE HELP!!!

Answer 1

For this case we have the following function:
 $f (x) = 0.01 * (2) ^ x$
 By definition, the average rate of change is given by:
 $AVR = \frac{f(x2) - f(x1)}{x2 - x1}$
 We evaluate the function for the given values:
 For x = 7:
 $f (7) = 0.01 * (2) ^ 7 f (7) = 1.28$
 For x = 14:
 $f (14) = 0.01 * (2) ^ {14} f (14) = 163.84$
 Then, replacing values we have:
 $AVR = \frac{163.84 - 1.28}{14 - 7}$
 $AVR = 23.22$
 Answer:
 the average rate of change from x = 7 to x = 14 is:
 a. 23.22
