Describe how y = f(x) is transformed by each of the
following:
y=—f(x÷2)—5 (3marks)

y =f(—x) + 5 (2 marks)

Respuesta :

Using translation concepts, it is found that the transformations are as follows:

  • In y = -f(x÷2) - 5, the function is reflected over the x-axis, horizontally stretched by a factor of 2 and shifted 5 units down.
  • In y = f(-x) + 5, the function is reflected over the y-axis and shifted 5 units up.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In y = -f(x÷2)-5, we have that:

  • f(x) is multiplied by -1, hence it was reflected over the x-axis.
  • x is divided by two inside the domain, hence the function was horizontally stretched by a factor of 2.
  • 5 is subtracted from f(x), hence the function was shifted 5 units down.

In y = f(-x) + 5, we have that:

  • x is multiplied by -1 inside the domain, hence the function was reflected over the y-axis.
  • 5 is added to f(x), hence the function was shifted 5 units up.
