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
No exception for x or y and hence set of all real numbers is domain and range.
f' becomes 0 not at finite points
So relative extreme
Graph is sketched and attached
12
12 +30= 42
42+12=54
yes
112
B
Class and cost per class should be multipled so must be A or B. The amount of money she has should be greater than or equal to her costs or she can't afford it! So B.
