Answer:
[tex]k=-5[/tex]
Step-by-step explanation:
If we observe the graph carefully there are two on each of the graphs highlighted at x=-2.The functions take the following values at that x.
[tex]f(-2)=2[/tex]
[tex]g(-2)=-10[/tex]
given the condition
[tex]g(x)=k*f(x)[/tex]
put [tex]x=-2[/tex]
we get . [tex]-10=k*2[/tex]
[tex]k=-5[/tex]
