Question

(look at the pictures)

Answer 1

Step-by-step explanation:

the function A, according to the tables

=> the equation : f(x) = 2x +3

the slope = 2

the function B, according to the graph

=> the equation : f(x) = 3x -2

the slope = 3

based on the value of the slope, the function B has a greater rate of change

Answer 2

Answer:

Step-by-step explanation:

Find the slope for the two functions

Function A:

(1 , 5)  & (2 , 7)

Slope = Change in y ÷ change in x

         $= \frac{7-5}{2-1}\\\\= \frac{2}{1}\\\\= 2$

Function B:

(1 ,1) , (2 , 4)

Slope = $= \frac{4-1}{2-1} = \frac{3}{1}$

             = 3

Function B has a greater rate of change
