Let the graph of g be a vertical shrink by a factor of 1/5 followed by a translation 8 units down of the graph of f(x) = x^2

Write a rule for g.


g(x) =

Respuesta :

Using translation concepts, it is found that the rule for g is:

[tex]g(x) = \frac{x^2}{5} - 8[/tex]

--------------------------------

  • The parent function is: [tex]f(x) = x^2[/tex].
  • Shrinking a function f(x) vertically by a factor of [tex]0 < a < 1[/tex] is equivalent to: [tex]a \times f(x)[/tex]
  • f(x) by a factor of 1/5:

[tex]\frac{1}{5} \times f(x) = \frac{1}{5} \times x^2 = \frac{x^2}{5}[/tex]

  • Shifting a function down a units is the same as finding [tex]f(x) - a[/tex].
  • Down 8 units, then, the rule for g is:

[tex]g(x) = \frac{x^2}{5} - 8[/tex]
