Determine a series of transformations that would map figure H onto figure I

Your answer would be A reflection over the x-axis followed by a rotation of 90° counterclockwise about the origin.

Step-by-step explanation: Since you would first rotate over the x- axis and then rotate it by 90 degrees counterclockwise over  the origin

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
