Question: how to show this

show that (3/x)/x+3 = 3/x(x+3) these are shown in fractions.-(3/x) / (x+3) = 3/[x(x+3)] (3/x)[1/(x+3)] = 3/[x(x+3)] 3/[x(x+3)] = 3/[x(x+3)] Basically, you leave one side alone and work on the other

Is the function odd even or neither

f(x)=cube root of x-Its odd because f(-x) always equals -f(x). For example ³√(8) = 2 and ³√(-8) = -2. The graph has 180° rotational symmetry about the origin. I hope this helps.-odd power (1/3) odd fu

What is the geometrical significance of a in y=ax^3

May you also comment on the sign of a and the size of a. thanks-If a > 0, then y = ax^3 will make the cubic go uphill, that is, start from the bottom left corner and go to the top right corner. If a
