the above is a function
Step-by-step explanation:
function is a mapping from a set A to B, which associative every element of A with unique image in B.

Answer:
9.750
Step-by-step explanation:
formula for average rate of change is ;
f(b)- f(a)/b- a
here a = 1 and b = 2.5
f(b) = (2.5)^3 + 2 = 17.625
f(a) = 1^3+ 2 = 3
using the formula above, we have it that
(17.625-3)/2.5-1 = 9.750
