Question

Evaluate p left parenthesis x right parenthesis equals 2 square root of x for the variable x = 3 to the nearest hundredth.

  1. 3.46
  2. 3.64
  3. 0.36
  4. 0.34

hintHint:

A function that maps the set of nonnegative real numbers onto itself. In geometrical terms, the square root function maps the area of a square to its side length.

The correct answer is: 3.46


    We have to find the value of p(x) = 2√x when x = 3 to nearest hundredths.
    We have, p left parenthesis 3 right parenthesis equals 2 square root of 3 equals 2 cross times 1.73 almost equal to 3.46
    Hence, the correct option is A.

    To find the value of a function, we have to put the value of the variable given.

    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
