Final answer:
The average rate of change of the function y=4x² from x=0 to x=7/4 is calculated by finding the change in y and the change in x, then dividing the two. The result is 7.
Step-by-step explanation:
To find the average rate of change of the function y=4x² over the interval from x=0 to x=7/4, we use the formula for the average rate of change, which is:
average rate of change = (change in y) / (change in x)
First, we calculate the value of the function at the start and end of the interval:
- y(0) = 4(0)² = 0
- y(7/4) = 4(7/4)² = 4(49/16) = 49/4
Then, we find the change in y and the change in x:
- Change in y: y(7/4) - y(0) = 49/4 - 0 = 49/4
- Change in x: (7/4) - 0 = 7/4
Now, we can calculate the average rate of change:
average rate of change = (49/4) / (7/4) = 49/7 = 7
Therefore, the average rate of change of the function y = 4x² from x = 0 to x = 7/4 is 7.
