4. The cube root parent function is vertically stretched by a factor of 3, reflected in the x-axis,
then translated 8 units down. Write an equation to represent the new function.

Respuesta :

Using translation concepts, it is found that the equation that represents the new function is:

  • [tex]y = -3\sqrt[3]{x} - 8[/tex]

The cube root parent function is given by:

[tex]y = \sqrt[3]{x}[/tex]

Translation:

The function goes through these following translations:

  • Vertically stretched by a factor of 3, that is, it is multiplied by 3, hence [tex]y = 3\sqrt[3]{x}[/tex].
  • Reflected over the x-axis, that is, it is multiplied by -1, hence [tex]y = -3\sqrt[3]{x}[/tex].
  • Translated 8 units down, that is, 8 is subtracted from the function, hence [tex]y = -3\sqrt[3]{x} - 8[/tex].

Then, the equation is:

  • [tex]y = -3\sqrt[3]{x} - 8[/tex]
