Question

Determine the domain and range

Answer 1

Domain: [0, 4]

Range: [0, 64]

Remember, the domain is the set of all x-values that satisfy the function, meaning their is a corresponding y-coordinate for every x-coordinate in the domain. The range is the set of all y-value, showing the output range of the function. We use brackets in this case because we have defined points, hence the black dot.

Answer 2

Domain:

`0 \leqslant x \leqslant 4`

Range:

`0 \leqslant x \leqslant 64`
