Suppose f and g are functions such that g(x)=3f(2x) .
a. a What transformations are needed to map y=f(x) onto y=g(x) ?
b. b Find the image of each of these points on y=f(x) :
i (3,−5)
ii (1,2)
iii $(-2, 1)
c. c Find the point on y=f(x) which maps onto the image point:
i (2,1)
ii (−3,2)
iii $(-7, 3)
