Master Graphing a quadratic by converting from standard to vertex form by completing the square

What is the first step in converting a quadratic from standard form to vertex form?

• Determine the domain and range

• Graph the function

• Complete the square

• Identify the axis of symmetry

When completing the square, what operation is performed on the linear coefficient?

• Multiply by 2

• Divide by 2 and square it

• Subtract 1

• Add 1

Why is it important to subtract the value added inside the parentheses when completing the square?

• To change the function's value

• To keep the function's value unchanged

• To simplify the equation

• To find the axis of symmetry

What does the vertex form of a quadratic equation help you identify?

• The vertex of the parabola

• The y-intercept

• The slope of the line

• The x-intercept

How is the axis of symmetry determined from the vertex form?

• It is the y-coordinate of the vertex

• It is the x-coordinate of the vertex

• It is the sum of the coefficients

• It is the product of the coefficients

What is the domain of a quadratic function in vertex form?

• Numbers between -1 and 1

• Only positive numbers

• Only negative numbers

• All real numbers

What should you do if the coefficient of the quadratic term is not 1?

• Add it to the constant term

• Subtract it from the linear term

• Factor it out

• Ignore it

How does a coefficient greater than 1 affect the graph of a quadratic function?

• It shifts the graph to the right

• It shifts the graph to the left

• It compresses the graph horizontally

• It stretches the graph vertically

What is the range of a quadratic function that opens upwards?

• From negative infinity to the y-coordinate of the vertex

• From the y-coordinate of the vertex to infinity

• From zero to infinity

• From negative infinity to zero

What happens to the graph of a quadratic function when the coefficient of the quadratic term is negative?

• It becomes a circle

• It becomes a straight line

• It opens downwards

• It opens upwards
