According to the MiniLesson which of the following are TRUE

According to the Mini-Lesson, which of the following are TRUE about Quadratic Functions? Check all that apply. The equation for the axis of symmetry represents the Vertex The equation for the axis of symmetry represents the equation of a vertical line The input of the vertex can always be found using the equation x = -b/2a The Vertex is always the highest point on the graph The is of symmetry passes through the vertex According to the Mini-Lesson, which of the following are TRUE about Quadratic Functions? Check all that apply. The Horizontal Intercepts are found by using the equation x = -b/2a The Domain of a Quadratic Function is All Real Numbers The Domain of a Quadratic Function is x > -b/2a One way to find the Horizontal Intercept is to use the intersect feature on a graphing calculator The Range of a Quadratic Function is from its lowest point to infinity if the coefficient a is negative

Solution

1A) b , c, e

Axis always represents a vertical line. ( There is always an excetion if parabola is horizontal. Then axis is not vertical. But most function have y = ax^2 +bx+c form axis is vertical)

Vertex can be highest ot lowest point

2A) b , d

Range is highest point to - infinity if coefficient is negative
