The graph of g is a vertical stretch by a factor of 4 and a reflection in the x-axis, followed by a translation 2 units up of the graph of f(x)=x2. Write a rule for g. Then identify the vertex.

Respuesta :

Answer:

f(x)=x^2

g(x)= -4(x^2)+2

(0,2)

Step-by-step explanation:

Using transformation concepts, it is found that:

  • The rule for g is: [tex]g(x) = -4x^2[/tex]
  • The vertex is: (0,0).

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

  • Stretching a function [tex]f(x)[/tex] vertically by a factor of b is given by: [tex]g(x) = bf(x)[/tex]
  • Reflecting a function over the x-axis is the equivalent of: [tex]g(x) = -f(x)[/tex]

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

  • The original function is: [tex]f(x) = x^2[/tex].
  • Stretching by a factor of 4 means that the function is multiplied by 4, thus: [tex]g(x) = 4x^2[/tex]
  • Reflecting over the x-axis, that is, multiplying by -1, we have that: [tex]g(x) = -4x^2[/tex], which is the rule for g.
  • From the graph added at the end of this answer, the vertex is at (0,0).
