+18 A function f is defined on the complex numbers by f(z) = (a+bi)z, where a and b are positive real numbers. Each point in the image of f is equidistant from the point z and the origin. Given that |a+bi| = 8, find a and b. Enter your answer as an ordered pair: (a,b)
I tried this question by plugging it in but apparently, I'm not getting the correct answer.. can someone please help??
