The average rate of change is also known as the slope. If we are looking to find the average rate of change between x = -1 and x = 2, in order to find the slope between those 2 x values, we need the y's that go along with them. Fill in -1 for x in the function and solve for y: . That means that the coordinate is (-1, 0). Fill in 2 for x in the function and solve for y: . The coordinate there is (2, -3). Now we can set up the slope formula to find the average rate of change between those 2 points: . Therefore, the average rate of change between x = -1 and x = 2 is -1
Since it is on sale of 25% then it is 25% off. So minus 100% by 25% which is 75% Then u find 75% of 44 the. Then answer you get it is the final answer.
