Fill in the Blank: For a direct non-linear power proportion $y = kx^n$ (with $k > 0$), the graph is symmetric about the $y$-axis and forms a U-shaped curve if the exponent $n$ is ________.

If ${y}$ is inversely proportional to ${x}$, and the value of ${x}$ is divided by $5$, what is the effect on the value of $$?

True or False: In the power proportion $y = kx^n$, if $n$ is an even integer (like $n=2$), the graph will be symmetric about the -axis.

Which of the following describes the characteristic shape of an inverse proportion graph in the first quadrant?

The variable ${y}$ is directly proportional to ${x}$. Given that ${y = 10}$ when ${x = 4}$, find the value of when .
