Front

Does this graph have a maximum or minimum value?

Back

minimum

Front

What is the range of this function?

Back

[-2, +∞)

Front

Quadratic equations take the shape of a _______ when graphed.

Back

parabola

Front

Use the graph to determine the X-intercepts: What are the X-intercepts of the function?

Back

(1,0) and (3,0)

Front

What is the standard form of a quadratic function?

Back

f(x) = ax^2 + bx + c

Front

What does the vertex of a parabola represent?

Back

The maximum or minimum point of the quadratic function.

Front

How can you determine if a quadratic function opens upwards or downwards?

Back

If 'a' (the coefficient of x^2) is positive, it opens upwards; if negative, it opens downwards.

Front

What is the axis of symmetry in a quadratic function?

Back

The vertical line that divides the parabola into two mirror images, given by x = -b/(2a).

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x-h)^2 + k, where (h,k) is the vertex.
