Three Types of Quadratics

Is this function Linear, Exponential, or Quadratic?

How many solutions are there?

• 2 imaginary

• 1 repeated real

• 2 real

• 0

For the function below, is the discriminant positive, negative, or zero?___________y = x² + 4x + 4

• Positive

• Negative

• Zero

• Not Sure

Convert the following graph into vertex form:

Match the following forms of equations with their correct descriptions.

• Vertex form of a quadratic equation

• y = ax² + bx + c

• Slope-intercept form of a linear equation

• y = a(x - h)² + k

• Standard form of a quadratic equation

• y = mx + b

Answer explanation

The correct choice is y = a(x - h)^2 + k, which represents the vertex form of a quadratic equation with the vertex at (h, k).
