14

Step-by-step explanation:

Average rate of change is given as

Where,

a = 4,

f(a) = f(4) = (4)² + 3(4) = 16 + 12 = 28

b = 7,

f(b) = f(7) = (7)² + 3(7) = 49 + 21 = 70

Plug in the values into the formula

Average rate of change =

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
