Pls help with this one no wrong answers pls ;-;

Answers below.

Step-by-step explanation:

Inititally as x increases, y remains the same.

Afterword, the slope = 2 for x = 3 to x = 5.

the slope = 1 for x =5 to x =9.

the greatest value of y is y = 4 when x = 5.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

f(x)=2/3x-8, which give g(x) the greatest value.
