Which composition of similarity transformations maps polygon abcd to polygon a'b'c'd'? a dilation with a scale factor less than 1 and then a reflection a dilation with a scale factor less than 1 and then a translation a dilation with a scale factor greater than 1 and then a reflection a dilation with a scale factor greater than 1 and then a translation

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

The graph of g(x) is a translation of y = which equation represents g(x)?
