Question

Please Help ! Its a math problem !!! Given the tables below, what is the difference between the average rates of change over the interval [1, 4]?

Answer 1

-4

Explanation:

Average rate of change (Table 1) :

• A(x) = h(4) - h(1) / 4 - 1
• A(x) = 9 - 3 / 4 - 1
• A(x) = 6/3 = 2

Average rate of change (Table 2) :

• A(x) = j(4) - j(1) / 4 - 1
• A(x) = 0 - 6 / 4 - 1
• A(x) = -6/3 = -2

Difference : -2 - 2 = -4
