Quadratic

The standard form of a quadratic equation is:

• y = ax + bx + c

• y = ax² + bx + c

• y = ax - bx - c

• y = a + b + c

The curve formed by a quadratic equation is called a

• paragraph

• paradigm

• octopus

• parabola

The formula for axis of symmetry is:

• x = -b/2a

• x= b/2

• x = -b/1a

• x = y

If the vertex is the highest point on the graph, it is called the:

• minimum

• max

• maximum

• min

If the vertex is the lowest point on the graph, it is called the:

• minimum

• min

• maximum

• max

Would the parabola go up or down for this equation & why?

y = -x¹ - 1x + 3

• Down because the 1 in b is negative (-1x)

• Down because the 1x in a is negative (-x¹)

• Up because the y is positive

• Up because the 3 in c is positive (+3)
