What, if anything, did Ryan do wrong when graphing this equation?

He graphed a circle with a radius of 25 instead of a radius of 5.

He graphed a circle with center at (5, 0) instead of at (-5, 0).

He graphed a circle with center at (5, 0) instead of at (25, 0).

Ryan’s graph is accurate.

Answer 1

He graphed a circle with radius of 25 instead of a radius of 5
