Solve the problem down below:

ty :P

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
