1.
Determine if the function graphed has a maximum or a minimum value and identify that value.
a)
maximum at -1
b)
minimum at -1
c)
maximum at 4
d)
minimum at 4
2.
What is the arrow pointing at? How can you use this value to determine the minimum/maximum values?
a)
The arrow is pointing at the y-intercept. The y value of this point is equivalent to the maximum/minimum
b)
The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum
c)
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
d)
The arrow is pointing at the vertex. The y value is equivalent to the minimum/maximum
