Two functions, a and b, are described as follows: function a y = 9x + 4 function b the rate of change is 3 and the y-intercept is 4. how much more is the rate of change of function a than the rate of change of function b? 2 3 6 9

The rate of change of function A is 6 more than the rate of change of function B and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the correct

Step 1 - Remember that the rate of change is nothing but the slope of the given function.

Step 2 - Now, determine the rate of change of function A. The slope of function A is 9 so, the rate of change is 9.

Step 3 - According to the given data, the rate of change of function B is 3.

Step 4 - Compare the rate of change of both the function A and B.

Step 5 - From, the above steps it can be concluded that the rate of change of function A is 6 more than the rate of change of function B.

Therefore, the correct option is C).
