Answer:
Option C.
Step-by-step explanation:
Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.
Consider the given function is
If 
, then 
is an even function.
If 
, then is an odd function.
Now, substitute x=-x in the given function.
So, the given function not an odd function. It means it is an even function.
To check whether the given function is odd, we have to determine whether 
is equivalent to 
.
Therefore, the correct option is C.
Answer:
let t = no of minutes when they are at the same altitude
:
52200 - 3300t = 2500t
52200 = 3300t + 2500t
52200 = 5800t
t = 52200/5800
t = 9 minutes they will be at the same altitude
:
The altitude:
9*2500 = 22500 ft
:
Check on other train
52200 - 9(3300) =
52200 - 29700 = 22500 ft

Answer:
x^2 - 7x - 1
Step-by-step explanation:
g(x) = x^2– 5x
f(x) = 2x +1
(g - f)(x)
expand to get
gx - fx
Slot in the values
(x^2– 5x) - (2x +1)
expand
x^2 - 5x - 2x - 1
x^2 - 7x - 1
we know that the quatraitic equation
we know that the quadratic equation is aX square + bx + c we put this value A and B and C in equation X square + bx + c
