What you practice

These are the Grade 9 Functions & Notation skills this quiz is built around.

Evaluate f(x) and solve f(x) = k for an input k.
State domain restrictions such as a denominator not equal to zero.
Compare linear, quadratic, and exponential graphs by rate of change.

A useful tip

The domain of a quotient excludes x-values that make the denominator zero. Setting the denominator equal to zero finds those excluded inputs; it does not solve the function's value.
