Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

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.

Which graph represents the parent function of y=(x+2)(x-2)
