Answer:
Step-by-step explanation:
Using the graph we can notice something
let's take the abscissa -2 and -4
- the ordinate that goes with -2 using g is 0
- the ordinate that goes with -4 using f is 0
so we can say that :
f(-4)=g(-2)
wait we khow that g(x)=f(k*x)
so x= -2 then let's replace it in the expression : f(k*x)
we get f(-4)=g(-2)=f[k*(-2)]
let's solve the equation: -2k = -4
k = -4/-2
k=2
so finally we get k=2
let's check :
from the graph we get :
we have (-1)*2 = -2
so it is true
