How to Find f(x) and g(x) of y = 2/x^2 + 3

Aregular hexagon rotates counterclockwise about its center. it turns through angles greater than 0° and less than or equal to 360°. at how many different angles will the hexagon map onto itself?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Which of the following is the inverse of y = 3∧x y = 1/3∧x y = ㏒3x y = (1/3) ∧x y = ㏒ 1/3∧x
