Concept:A mapping rule gives the relationship between each input $x$ and its corresponding output $y$.Substitute the given $x$-values into each option to see which rule produces the listed $y$-values.Explanation:Check option A: $x \longrightarrow 15x$.For $x = 1$: $15(1) = 15$, which matches $y = 15$.For $x = 2$: $15(2) = 30$, which matches $y = 30$.For $x = 3$: $15(3) = 45$, but the table shows $y = 46$.For $x = 4$: $15(4) = 60$, which matches $y = 60$.Every value matches exactly except the third one, which differs by only $1$.So the given $46$ is most likely a misprint for $45$.The other options do not fit the pattern for even the first two pairs.Therefore, the intended mapping rule is $x \longrightarrow 15x$.Answer:Option A: $x \longrightarrow 15x$
