The area between z = - 1 and z = 1.2 under the standard normal curve is O. (Round to four decimal places as needed.)

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.

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?

Use the second shift theorem to find the inverse laplace transform of (e^−3s) / (s^2 + 2s − 3)
