Use the discriminant to determine the number and types of roots of the quadratic equation., 4x2 - 71 +1 = -5 The discriminant is than 0, so there are ___ ___roots.

Which function is shown in the graph below?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
