Question
For the square root function 
, the average rate of change between x = 5& x = q is 0.185. What is the value of q?
- 8
- 9
- 10
- 11
Hint:
It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
The correct answer is: 10
Let q = 10,
Average rate 
Therefore, value of q = 10

Find the x-intercept and y-intercept of 
.
Here we used the concept of intercepts. The points on a graph where the graph crosses the two axes are known as the intercepts (x-axis and y-axis). The x-coordinate is the location where the graph crosses the x-axis, and the y-coordinate is the location where the graph crosses the y-axis. So the intercepts are x-intercept = – 1; y-intercept = 1
