The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]
The range are the possible output values of f(x)
We need to solve f(x) = 3.2x for each value in our domain
f(-4) = 3.2(-4) = -12.8
f(-2) = 3.2(-2) = -6.4
f(0) = 3.2(0) = 0
f(2) = 3.2(2) = 6.4
f(4) = 3.2(4) = 12.8
The answer to this is 2 nickles and 6 quarters
Answer:
Final simplified form is 
Step-by-step explanation:
We have been given an expression 
Now we need to simplify
and check which choice matches with simplified form of
.
You missed to provide the choices but still we simplify that.



When there is negative sign inside square root then we replace that by "i" iota.

Hence final simplified form is 
There must be 23 students in Ms.Gardner's class because 23 - 30%=6.9 so 7
students are in her class are in the play because if you look at
Mr.Logan's class he has 23 students to and there are aslo 7 students in
his class are in the play so Mr. Logan's class is basically is holding
Ms.Gardner's place
