Graphing Quadratic Functions in Standard Form Worksheet

Determine the domain and range of a quadratic function from its graph or equation.

Identify the x- and y-intercepts and vertex of a quadratic function.

Describe a quadratic function's end behaviour using limit-style notation.

Determine the increasing and decreasing intervals of a parabola.

Assign the four graphed problems first as a warm-up before the four equation-based problems, since reading a graph is a more concrete entry point than algebraic analysis.

Use the worked answer key to model interval notation for domain, range, and increasing/decreasing intervals before students attempt the equation-based problems independently.

Note the 'Version 2: Standard Form' label if seeking companion versions in other forms (vertex, factored) from the same creator.

Quadratic graph analysis — students read domain, range, intercepts, and vertex directly from four graphed parabolas.

Standard-form equation analysis — students algebraically determine intercepts, vertex, and end behaviour from four quadratic equations given in standard form.

Interval notation — students express domain, range, and increasing/decreasing intervals using interval notation.

End behaviour description — students describe a function's behaviour as x approaches positive and negative infinity.
