Write two ways to group and add 4+7+2

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.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5

Atransformation t : (x, y) (x-5,y +3) the image of a(2,-1) is
