Question

Need help I don’t understand what it means

Answer 1

b) - 10

Explanation:

Average rate of change:

To find the average rate of change, we have divide the change in y of f(x) , by the change in x(input).

`\sf \boxed{\text{\bf Average rate of change = $(f(b)-f(a))/(b-a)$}}`

a = 4 ; f(a) = -17

b = 6 ; f(b) = -37

`\sf Average \ rate \ of \ change = (-37-[-17])/(6-4)`

`\sf =(-37+17)/(2)\\\\=(-20)/(2)\\\\=-10`
