When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.

Solve 2x − 1 = 11 for x using the change of base formula log base b of y equals log y over log b.
