Question
Find the minimum point of the function 
.
- (9, -4)
- (-9, 4)
- (-9, -4)
- (9,4)
Hint:
The minimum value of square root is always 0, Find the minimum value of y and x .
The correct answer is: (-9, -4)
The minimum point of the function in the form .
The minimum value of square root is always 0.
So, x = -9 and y = -4 at minimum value.
So, the minimum point is (-9 , -4).

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
