Quiz 1.1:
Question:
Could the graph below represent \( x \) as a function of \( y\)?
What about \(y \) as a function of \(x \)?
Solution:
\( x \) is not a function of \( y \) because for the input \( y=1 \), there are \( 3 \) corresponding ouput,\( x \), values.
\( y \) is a function of \( x \) because each input of \( x \) corresponds to only one output of \( y \).
\( y \) is a function of \( x \) because each input of \( x \) corresponds to only one output of \( y \).
