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 trigonometric ratios sine and secant are reciprocals of each other

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year
