Answer:
The rate of change of function is: 2
Explanation:
Using the given table we have to exclude two pairs of input and output.
The rate of change or slope of function is given as:
![m = (y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/qpav2tpezfjoebw1smt5zxyas28f0tlb4m.png)
We take first two pairs of input/output from the table
(x1,y1) = (1,11)
(x2,y2) = (2,13)
Putting the values
![m = (13-11)/(2-1)\\m =(2)/(1)\\m = 2](https://img.qammunity.org/2021/formulas/mathematics/college/tv54ja7utot7ncb8x0xr4r549lf363u529.png)
Hence,
The rate of change of function is: 2
