The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coefficients.
If g(x) = k(f(x), what is the value of k?
Notice on f(x), the indicated points are (0,1) and (1,1)
Also, on g(x), the indicated points are (0,3) and (1,3) The question is, what are you multiplying the yvalue on f(x) to get the corresponding yvalue on g(x)? In other words, what do you multiply 1 by to get 3, in both sets of corresponding points? k = 3 When multiplying f(x) by 3,  the negative sign indicates a reflection over the xaxis, as you are taking the negative of the yvalue  the 3 indicates a stretch, away from the xaxis, by a factor of 3, as you are multiplying the yvalue by 3 Ask Algebra House Comments are closed.
