If there are two unequal real roots of equation (1 / 2) ^ (absolute value (x-1)) = m, find the value range of M

If there are two unequal real roots of equation (1 / 2) ^ (absolute value (x-1)) = m, find the value range of M

(1 / 2) ^ | X-1 | = m has two unequal real roots
That is, the image of the function y = (1 / 2) ^ | X-1 | has two intersections with the straight line y = M
When x1, y = (1 / 2) ^ (x-1) the decreasing range of function is (0,1)
When x = 1, ymax = 1
The equation has two unequal real roots,
Then the value range of M is (0,1)
