Question

Write an expression for the function which has a translation by 3 units up of f(x) = square root of x.

  1. square root of x space minus space 3 end root
  2. square root of x space plus space 3 end root
  3. square root of x space plus space 3
  4. square root of x space minus space 3

hintHint:

Translating  up means adding the k unit the value of y .

The correct answer is: square root of x space plus space 3


    Translating up means adding the 3 unit the value of f(x).
    Then the expression for the function which has a translation by 3 units up of f(x) = square root of x is square root of x space plus space 3.

    Find the x-intercept and y-intercept of y equals square root of x minus 2.

    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 = 4; y-intercept = -2
