Ijust need you to answer a for me, i have no clue what the equivalent expression is, !

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.

What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi
