Question

Quizplus · Accepted Answer

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

Answer: B) Vertex 
 To find the vertex, use the formula: x = -b/2a and y = f(x).

Answer: C) Maximum or minimum 
 To determine if the function has a maximum or minimum, check the leading coefficient of the quadratic function. If it's positive, the function has a minimum, and if it's negative, the function has a maximum.

Answer: D) Range 
 To find the range, analyze the shape of the parabola and whether it opens up or down. The range will be all values greater than or equal to (or less than or equal to) the y-coordinate of the vertex, depending on the direction of the opening.
