Question 893516: If f(-5)=-2 and g(x)= -2*f(x), what point can you determine on the graph of g?
I've tried plugging in both -5 and -2, this is my first time doing this and i know what in doing it completely incorrect. Can you help?

You can put this solution on YOUR website!
g is a function of f, and f is a function of x. Your input for f is -5. You can then find the point for g when f(x) is given x=-5.

The ONLY point you can find on g is g%28-5%29=-2%2Af%28-5%29=-2%2A%28-2%29=4.
This then is the point, (-5,4).
