Key Concepts
The coefficient $a$ in the function $f(x) = ax^2$ affects the graph of $f(x) = x^2$ by stretching or compressing it vertically. If $0 < a < 1$, the graph of $f(x) = ax^2$ will be "wider" than the graph of $f(x) = x^2$. If $a 1$, the graph of $f(x) = ax^2$ will be "skinnier" than the graph of $f(x) = x^2$.
