Answer:
Step-by-step explanation:
b. y = sin x
c. y = sec x
d. y = cos x
The function is even will be y = sec x and y = cos x. Then the correct options are C and D.
Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.
The equation should be stored in an even function:
f(-x) = f(x)
Check all that apply.
a. y = csc x, then replace x with -x. Then we have
y = csc -x
y = 1/sin -x
y = - 1/ sin x
y = -csc x
b. y = sin x, then replace x with -x. Then we have
y = sin -x
y = - sin x
c. y = sec x, then replace x with -x. Then we have
y = sec-x
y = 1/cos -x
y = 1/ cos x
y = sec x
d. y = cos x, then replace x with -x. Then we have
y = cos -x
y = cos x
Thus, the function is even will be y = sec x and y = cos x.
Then the correct options are C and D.

Domain of (f-g)(x) = (-∞, ∞)
3.
Substitute the values of the given functions.
The function is a polynomial which is defined for all real values x.
Domain of (fg)(x) = (-∞, ∞)
4.
Substitute the values of the given functions.
The function is a rational function which is defined for all real values x except 0.
Domain of (f/g)(x) = (-∞,0)∪(0, ∞)
, domain: all real numbers.
, domain: all real numbers.
, domain: all real numbers.
, domain: all real numbers.
To find (f + g)(x), we need to add the functions f(x) and g(x).
The function f(x) = x - 3 and the function
So,
Expanding this equation, we get
To find the domain of (f + g)(x), we need to consider the domain of the individual functions f(x) and g(x).
Since both f(x) = x - 3 and are defined for all real numbers, the domain of (f + g)(x) is also all real numbers.
To find (f - g)(x), we need to subtract the function g(x) from f(x).
So,
Expanding this equation, we get
The domain of (f - g)(x) is also all real numbers, since both f(x) and g(x) are defined for all real numbers.
To find (fg)(x), we need to multiply the functions f(x) and g(x).
So,
Expanding this equation, we get
The domain of (fg)(x) is all real numbers, since both f(x) and g(x) are defined for all real numbers.
To find f(g(x)), we need to substitute g(x) into the function f(x).
So,
The domain of f(g(x)) is also all real numbers, as is defined for all real numbers, and f(x) = x - 3 is defined for all real numbers.
In summary:
- , domain: all real numbers.
- , domain: all real numbers.
- , domain: all real numbers.
- , domain: all real numbers.

Answer:
5.5+7.25−5.5−7.25 = 0
Step-by-step explanation:
To be honest, you shouldn't have to show work for an equation like this. But this is the answer. Hope it helped.
Answer:
5.5+7.25-5.5+(-7.25)
step 1: add 5.5 and 7.25
12.75−5.5−7.25
step 2: subtract 5.5 from 12.75
7.25−7.25
The answer is 0.
