Look at the attached for function 2.
Which function has a larger maximum? Type your answer as 1 or 2. (2 points)

Answer 1

the answer is 1! I just took the quiz :)

Answer 2

1

Explanation:

Function 1:

x = - b/ 2 a = 6 /8 = 3/4

f ( 3/4 ) = - 4 * 9/16 + 6 * 3/4 + 3 = - 9 /4 + 18 / 4 + 3 = 2.75 + 3 = 5.25

y max = 5.25

Function 2:

y max = 3 ( from a picture )

The 1st function has a larger maximum ( 5.25 > 3 )
