Linear function a and linear function b both have the same input values as shown below. why will the output values for linear function a always be different than the corresponding output values for linear function b? the initial values of the two functions are different, and the rates of change of the two functions are also different. the initial values of the two functions are different, and the rates of change of the two functions are the same. the initial values of the two functions are the same, and the rates of change of the two functions are different. the initial values of the two functions are the same, and the rates of change of the two functions are also the same.
