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 ${y}$ ?

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 $y$ -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 ${y}$ when ${x = 7}$ .

${y}$ is multiplied by $5$

${y}$ is decreased by $5$

${y}$ is multiplied by $25$

${y}$ is divided by $5$
