Question

(08.05 MC)

Functions 1 and 2 are shown:
Function 1: f(x) = -4x² + 6x + 3
Y
Function 2
N
2
Which function has a larger maximum?

Answer 1

The function from the above scenario that has a larger maximum is function 1.

What is the function about?

Note that the first function is;

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

The second Function is:

y max = 2

Therefore we can see that the first function has a larger term that is ( 5.25 > 2 ).
