Please someone help me with this question for 4th grade thank you

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.

Evaluate the expression. (9 + 5)(3 + 2)0

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle
