Answer:
Options (1) and (5)
Step-by-step explanation:
Expression that defines the function is,

Option 1





So,
is false.
Option 2
f(0) = 
= 
True.
Option 3
f(1) = 
= 
= 2
Therefore, f(1) = -1 is false.
Option 4



Therefore, f(2) = 1 is false.
Option 5
f(4)



True.
Options (1) and (5) are the correct options.
80 1.5 because 10 times 8 equals 80 plus 1.5 equals 80.1.5
Since we are solving for h, the equation:
V = πr²h
...divides πr² to the other side. Thus, it becomes....

= h
Which can be rewritten as....
h =
