Answer:
Step-by-step explanation:
Given is a function f(x)

We have to analyse and sketch the graph
X intercept : Put y =0, we get x=0
Y intercept: Put x =0 , we get y =0

f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
Okay so -6 + Y = 0
Y = his total score on the first day
so you can do 0- (-6)= Y
answer Y= 6
first day he got a score if 6
