To answer this question, the lens equation needs to be used, which has the following formula: 1/f = 1/d_o + 1/d_i Where: f is the focal length d_o is the object distance d_iis the image distance. Solve for the image distance: 1/f = 1/d_o + 1/d_i 1/1.75 m = 1/1.5 m + 1/d_i 0.57 m^-1- 0.67 m^-1= 1/d_i -0.1 m^-1 = 1/d_i d_i= - 10 m A negative image distance means that the image is on the same side of the mirror lens as the object.
