Medal + Fan for answer & explanation.

What transformations change the graph of f(x) to the graph of g(x)?
F(x) = -7x^2
G(x) = -35x^2 + 5

A) The graph of g(x) is the graph of f(x) stretched vertically by a factor of 1/5 and translated down 5 units.
B) The graph of g(x) is the graph of f(x) stretched vertically by a factor of 5 and translated down 5 units.
C) The graph of g(x) is the graph of f(x) stretched vertically by a factor of 1/5 and translated up 5 units.
D) The graph of g(x) is the graph of f(x) stretched vertically by a factor of 5 and translated up 5 units.

How do you get from 7 to 35? What factor is that?

benji · Answer

And once you know that factor, there are only 2 options it can be. So the +5 is a positive translation, so do you think it will go up or down 5 units?

love_333 · Answer

The factor is... 5? And +5 so up?
Sorry I've never studied this until today so I don't know how to do it.

benji · Answer

You are right.
