Properties of Quadratic Graphs from Equations (Day 2)

Standard Form

Multiple Choice

Standard form of a quadratic equation

• y=x²
• y=ax²+bx+c
• y=mx+b
• y=x

Properties of the Quadratic Parent Function

• Opens Upward like a "U"

• Vertex at (0,0) (The Origin)

• Symmetrical about the y-axis

Multiple Choice

Which parent function matches the graph?

• y = |x|
• y = ∛(x)
• y = x²
• y = a⋅b^x

When "a" is positive, the parabola opens Upwards.

When "a" is negative, the parabola opens downwards.

Multiple Choice

How does the parabola open? y = 4x - x² - 1

• up

• down

• left

• right

Multiple Choice

A parabola is upside-down when a is:

• negative
• positive
• 0
• infinite

Multiple Choice

*Pay attention to where x² is located.*

• Up

• Down

• Left

• Right
