Given a graph for the transformation of f(x)=f(kx), determine the k value



a
k=-1/3
b
k=1/3
c
k=-3
d
k=3

Given A Graph For The Transformation Of Fxfkx Determine The K Value A K13 B K13 C K3 D K3 class=

Sagot :

Answer:

  • B. k = 1/3

Step-by-step explanation:

Compare any two points on same horizontal line.

The easy one is:

  • f(-3) = g(-1) = - 3

Since g(x) = f(kx), substitute the x- coordinates to find the value of k:

  • - 1 = k*(-3)
  • k = - 1/ - 3
  • k = 1/3

Correct choice is B
