Answer:
C
Step-by-step explanation:
The maximum/minimum values is simply the y-value of the vertex. Since both of the functions have a negative leading coefficient, they will both have maximum values.
For Function 1, we can see that the vertex is at (4,1). Thus, it's maximum value is at y=1.
For Function 2, we need to work out the vertex. To do this we can use:
To find the vertex.
Function 2 is defined by:
Therefore:
Thus, the vertex of Function 2 is at (2,5). Therefore, the maximum value of Function 2 is y=5.
5 is greater than 1, so the maximum value of Function 2 is greater.
The answer is choice C.
