WebThe range tells us that the inverse function has a minimum value of y = -3 y = −3 and a maximum value of y = 0 y = 0. The positive square root case fails this condition since it has a minimum at y = 0 y = 0 and maximum at y = 3 y = 3. The negative case must be the obvious choice, even with further analysis. WebStep 1: Flip both sides of the equation. Step 2: Check the unit circle. If the value is a multiple of a known coordinate, check that the angle is within the limits given in the question. Otherwise,...
