What’s the answer for this?

Ineed with this math problem p(65)=500×1.0325*65 the star means that you have to times it like 1.0325×1.0325?

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 axis of symmetry of the function f(x)=-(x+ 9)(x-21)
