Question

Find the minimum point of the function f left parenthesis x right parenthesis equals square root of x plus 9 end root minus 4.

  1. (9, -4)
  2. (-9, 4)
  3. (-9, -4)
  4. (9,4)

hintHint:

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  f left parenthesis x right parenthesis equals square root of x plus 9 end root minus 4.
    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 y equals square root of x plus 1 end root .

    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
