Question

Which functions have an additive rate of change of 3? check all that apply

Answer 1

Answer: Table 2 and table 3 are the functions which have an additive rate of change of 3.

Step-by-step explanation:

The rate of change of a linear function is given by:-

$R=\frac{y-2-y_1}{x_2-x_1}$

For table 1,

$\\\Rightarrow\ R=\frac{-9-(-3)}{4-2}\\=\frac{-9+3}{2}\\=\frac{-6}{2}\\=-3$.....> which is not positive.

For table 2,

$\\\Rightarrow\ R=\frac{-1-(-4)}{3-2}\\=\frac{-1+4}{1}\\=\frac{3}{1}\\=3$.....> which is positive.

For table 3,

$\\\Rightarrow\ R=\frac{10-1)}{5-2}\\=\frac{9}{3}\\=3$.....> which is positive.

Hence, Table 2 and table 3 are the functions which have an additive rate of change of 3.
