Madison created two functions.

for function a, the value of y is two less than four times the value of x.

the table below represents function b.
-3,-9
-1,5
1,-1
3,3

in comparing the rates of change, which statement about function a and function b is true?

a.

function a and function b have the same rate of change.
b.

function a has a greater rate of change than function b has.
c.

function a and function b both have negative rates of change.
d.

function a has a negative rate of change and function b has a positive rate of change.

Step-by-step explanation:

The value of y is two less than four times the value of x.

This statement can be expressed as

This linear function is expressed as slope-intercept form. Where the slope is

This function is represented by the given table.

If you observe, the domain is defined as -3, -1, 1, 3. The range is defined as -9, -5, -1, 3.

The domain values increase two units. Range values increase by 4. So, the ratio or slope of this function is

If we compare the ratio of change (or slopes) of both function, we would find that Function A as a doble ratio of change than Function B. In other words, Function A has a greater rate of change than Function B.

Therefore, the right answer is B.

no this is a nonlinear negative
