Question

Help me pls what is the rate of change and the function​

Answer 1

Explanation:

Rate of change of a function between x = b and x = a,

Rate of change =
`(f(b)-f(a))/(b-a)`

From the given table,

Rate of change of the given function between x = 3 and x = 5,

f(5) = -26

f(3) = -2

Rate of change =
`(-26+2)/(5-3)`

= -12

Since, rate of change for the given function is constant, function is a linear function.
