*Give your answer as a fraction.
d)
When $x$ is the input, what is the output?
The function represented as a set of ordered pairs
a)
Fill in the blank: $\left(0,\square\right)$
b)
Fill in the blank: $\left(-1,\square\right)$
c)
Fill in the blank: $\left(x,\square\right)$
The function represented as a mapping
Is this an example of a "one-to-one", "many-to-one" or "one-to-many" mapping?
The function represented as a graph
If all the numbers from $-\infty$ to $\infty$ were put into the function,
the graph would be a line with the equation $y=$
the graph would be a line with the equation $y=$
