Alg Introduction to Quadratics

The curve formed by the quadratic equation is called the __________.

• Vertex

• Parabola

• Parachute

• Axis of Symmetry

What is the vertex of a parabola?

• The max or min

• The point the line of symmetry goes through

• The point that is the same distance from both x-ints

• All of the above

When does a quadratic open downward?

• when a is positive

• when a is negative

• it never opens downward

• when there is no b term

The Standard Form of a Quadratic Equation looks like this:

• ax² + bx + c= 0

• ax² + bx = c

• ax² + bx² + c= 0

• ax + bx + c= 0

In the Quadratic Equation 2x² + 5x + 3 = 0, what is the value of a?

• 1

• 2

• 3

• 5

In the Quadratic Equation 10x² - 4x + 5 = 2, what is the value of b?

• 10

• -4

• 5

• 2

What is the standard form of the quadratic equation, 5x² = 3x - 4

• 5x² + 3x + 4 = 0

• 5x² - 3x + 4 = 0

• 5x² + 3x - 4 = 0

• 5x² - 3x - 4 = 0

what is the value of a in the Quadratic Equation, 2x² -3x + 1 = 0

What is the value of b in the Quadratic Equation, -5x² +3x +1 = 0

What is the value of b in the Quadratic Equation 3x² - 4x = 2x -1
