1) Let F, G, and H be collinear points on the Cartesian plane such that FG/GH = 1. If F = (a, b) and H = (7a, c), then what is the x-coordinate of G?

2) The points (0,4) and (1,3) lie on a circle whose center is on the x-axis. What is the radius of the circle?

I'm really stuck on these...Can someone help? Thanks in advance!

I’m really stuck on this problem:

Suppose f(x) is a function defined for all real x, and suppose f is invertible (that is the inverse of f(x) exists for all x in the range of f).

If the graphs of y=f(x^2) and y=f(x^4) are drawn, at how many points do they intersect?

Thanks in advance!

I'm really stuck on this math problem...does anyone get it?

Given that f(3)=5 and f(3x)=f(x)+2 for all x, find the inverse of f(11).

Thanks in advance! smile
