Unit 4B Flashcardizz Test Review

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the vertex of a parabola in the form y=a(x-h)^2+k?

Back

The vertex of the parabola is the point (h, k). It represents the maximum or minimum point of the parabola.

Front

How do you find the y-intercept of a quadratic function?

Back

To find the y-intercept, set x=0 in the quadratic function and solve for y.

Front

What is Factored Form of a quadratic function?

Back

Factored Form is expressed as y=a(x-p)(x-q), where p and q are the x-intercepts of the function.

Front

How do you find the x-intercepts of a quadratic function?

Back

To find the x-intercepts, set y=0 in the quadratic function and solve for x.

Front

What is the standard form of a quadratic function?

Back

The standard form is y=ax^2+bx+c, where a, b, and c are constants.

Front

What does the 'a' value in a quadratic function indicate?

Back

The 'a' value determines the direction of the parabola: if a>0, it opens upwards; if a<0, it opens downwards.

Front

What is the significance of the 'h' and 'k' in vertex form?

Back

In vertex form y=a(x-h)^2+k, 'h' is the x-coordinate and 'k' is the y-coordinate of the vertex.

Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that passes through the vertex of the parabola, given by the equation x=h.

Front

How can you convert from standard form to vertex form?

Back

You can convert by completing the square on the standard form equation.
