Answer:
A.) Even.
Step-by-step explanation:
If a function is an even function, then 
F(-x) = f(x)
Also, if a function is an odd function, then, f(-x) = -f(x)
You are given the below function 
f(x) = 1 + 3x^2 − x^4
Let x = 2
Substitute 2 for x in the function 
F(x) = 1 + 3(2)^2 - (2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Also, Substitute -2 for x in the function 
F(x) = 1 + 3(-2)^2 - (-2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Since f(-x) = f(x), we can conclude that 
F(x) = 1 + 3x^2 - x^4 is even
 
        
             
        
        
        
Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2         Multiply by 2
2Area = (b1 + b2)*h           Divide by h
2Area/h = b1 + b2              Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27
It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.
 
        
             
        
        
        
2(x - 1) > = -12
2x - 2 > = -12
2x > = -12 + 2
2x > = -10
x > = -10/2
x > = -5 or -5 < = x
wrong solution would be B. x less then or equal to -5....because x is greater then or equal to -5
        
             
        
        
        
Hi there!
The answer is C.

The question has already revealed the following data:
x = number of tickets.
y = number of t-shirts.
We can now find the total cost function.
The cost of 1 ticket is $ 25
and therefore the total cost for all of the tickets is $25 × 
the amount of tickets, mathematically $25 × x, hence 25x.
The cost of 1 shirt is $ 12
and therefore the total cost for all of the tickets is $12 × 
the amount of shirts, mathematically $12 × y, hence 12y.
When making the total cost function, don't forget to include the service fee of $4.
Now we can conclude that the total cost function is the following:

Maya only has $130 and therefore the total cost must be smaller than or equal to this amount of money. The answer is C.
 
 
        
        
        
Answer:
Dear ishika
Answer to your query is provided below
She begin with 12 comic books.
Step-by-step explanation:
After reading question , you will get that she sell half of comic books ; that is (12/2) = 6 
And 
Bought = 8 books 
And 
now have 14 books
Verify = 
14 = 6+8
