Exploring Quadratic Functions

What type of function is introduced after linear functions?

• Quadratic functions

• Exponential functions

• Cubic functions

• Trigonometric functions

What shape is commonly associated with quadratic functions?

• Parabola

• Circle

• Ellipse

• Hyperbola

What is the vertex of a parabola?

• The highest or lowest point on the graph

• The point where the graph is widest

• The point where the graph crosses the y-axis

• The point where the graph crosses the x-axis

What does the axis of symmetry in a parabola represent?

• A horizontal line that cuts through the vertex

• A vertical line that divides the parabola into two symmetrical parts

• The peak point of the parabola

• The lowest point of the graph

Where does the axis of symmetry pass through in a parabola?

• Outside the graph

• At the x-intercept

• At the y-intercept

• Through the vertex

What is the correct expression for the axis of symmetry if the vertex is at (-3, 2)?

• y = 2

• x = -3

• x = 3

• y = -3

What is the y-intercept of a quadratic function?

• The point where the graph crosses the y-axis

• The highest point of the graph

• The lowest point of the graph

• The point where the graph is widest

What does the domain of a quadratic function typically include?

• All real numbers

• Only positive numbers

• Only negative numbers

• Numbers from zero to one

How is the y-intercept of a quadratic function determined from its graph?

• By finding the highest point of the graph

• By locating the vertex of the parabola

• By determining the widest part of the graph

• By identifying where the graph crosses the y-axis

In a quadratic function, if the vertex is the highest point, what does the range include?

• All y-values less than or equal to the vertex y-coordinate

• All y-values greater than or equal to the vertex y-coordinate

• Only positive y-values

• Only negative y-values
