About this resource

Eight quadratic-function problems ask students to determine each function's domain, range, x- and y-intercepts, vertex, increasing/decreasing intervals, and end behaviour -- the first four functions are presented as graphs to read directly, while the second four are given as standard-form equations such as f(x) = x^2 - 6x + 5, requiring students to work out the same characteristics algebraically. A fully worked answer key follows, showing every domain, range, intercept, vertex, and end-behaviour statement in interval notation for all eight functions. The worksheet is labeled 'Version 2: Standard Form,' implying it belongs to a series with other versions covering quadratics in different forms not included in this file. The mix of graph-reading and equation-analysis problems makes the set suitable as either an in-class practice set or a quiz on quadratic function characteristics.

Teaching tips & learning objectives

Learning objectives

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.

Teaching tips

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.

Skills covered

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.

Good to know

Questions teachers ask about this resource

Why are the first four problems different from the last four?

The first four give students a graphed parabola to read characteristics from directly, while the last four provide only a standard-form equation, requiring students to derive the same domain, range, intercepts, and vertex algebraically rather than by reading a picture.
