Understanding Parabolas and Quadratics

Asking a friend

Drawing the graph

Substituting values into the equation

Using a calculator

Vertical axis

Diagonal axis

Horizontal axis

None of the above

It shifts the graph upwards

It shifts the graph to the right

It has no effect

It shifts the graph downwards

ax^2 + bx + c

y = a(x - h)^2 + k

y = mx + b

x^2 + y^2 = r^2

x = 1

x = -1

x = 2

x = 0

y = 2

y = 0

x = 2

x = 0

y = a(x + h)^2 - k

y = mx + b

y = a(x - h)^2 + k

y = ax^2 + bx + c

By using the formula -b/2a

By drawing the graph

By substituting x = 0

By checking the y-intercept

The highest or lowest point

The point where the graph crosses the y-axis

The point where the graph crosses the x-axis

The midpoint of the graph

It provides a reference for the axis of symmetry

It is not important

It determines the slope of the graph

It helps in finding the y-intercept
