Maximum and Minimum of a Function

When the vertex is the highest point it is called ____

• the tipping axis

• absolute primo axis

• minimum

• maximum

A vertex that represents the LOWEST point on a graph is called _____

• maximum

• minimum

• vertex

• home run

Find the Vertex: y= x² +6x + 4 (HINT: Graph the equation on a calculator, then find the maximum or minimum.)

• (-3, -5)

• (5, 3)

• (3, 5)

• (5, -3)

Find the Vertex: y= x²- 4 . (HINT: Graph the equation on a calculator, then find the maximum or minimum.)

• (0,0)

• (0,4)

• (0,-4)

• (4,0)

What is the vertex?

• (-1,-2)

• (-2,-1)

• (-3,-1)

• (2,1)

Determine if the function graphed has a maximum or a minimum value and identify that value.

• maximum at -1

• minimum at -1

• maximum at 4

• minimum at 4

What is the arrow pointing at? How can you use this value to determine the minimum/maximum values?

• The arrow is pointing at the y-intercept. The y value of this point is equivalent to the maximum/minimum 

• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The y value is equivalent to the minimum/maximum

Does the equation have a max or min?
y = 2x² + 7x + 5

• max

• min

What do we call the highest or lowest point of a quadratic?

• parabola

• vertex

• graph

• point

The a value of this graph is

• negative

• positive

• impossible to tell

• 0
