Question

The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this.​ k = -3

Answer 1

Answer:

k = -3

Step-by-step explanation:

f(x) = -2x+1

g(x) = 6x - 3

=> g(x) = k.f(x)

6x - 3 = k(-2x+1)

k = (6x-3)/(-2x+1)

= 3(2x-1)/-1(2x-1)

k = 3/(-1) = -3
