Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?
