Which linear function has the greatest initial value and change.

Part A: Function C

Part B: Function B

Step-by-step explanation:

Part A:

Initial value of function A is the value of at .

Therefore, at

So, initial value of function A is 0.

Initial value of function B is given as:

Therefore, initial value of function B is -1.

Initial value of function C as seen in the graph is 2 because at .

Hence, on comparing the initial values of the three functions, function C has the greatest initial value.

Part B:

Rate of change of a function is given as:

For function A,

Therefore,

For function B, the coefficient of represents rate of change of the function.

Therefore, rate of change of function B is .

For function C, consider two points on the graph. Let the points be

Therefore, rate of change,

On comparing all the 3 rate of change, function B has the greatest rate of change of value 3.
