Question

Given f(x) and g(x) = f(k:x), use the graph to determine the value of k.

Answer 1

It should be 2

Explanation:

Answer 2

k=2

Explanation:

We are given that two function f(x) and g(x)

`g(x)=f(kx)`

From given graph

`g(-2)=0`

`f(-4)=0`

`g(-2)=f(-4)`

By comparing we get

x=-2 and

`kx=-4`

`k(-2)=-4`

`k=(-4)/(-2)=2`

Hence, the value of k=2
