Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

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}.

How does the graph of y = 3x compare to the graph of y = 3-x?
