You have a spherical mirror with a radius of curvature of+15cm (so it is concave facing you). You are looking at an object whose size you want totriplein the image, so you can see it better. Where should you put the object? Where will the image be? Will it be real or virtual? (Enter your object distances from smallest to largest. Indicate the location of the image with the sign of your answer.)
