Answer:
Domain of the function f(x) = cos x : ( - infinity , + infinity)
Step-by-step explanation:
Let the given function f(x) = cos x
We need to find the domain set of the given function f(x) = cos x
Domain is the set of all possible value of x for which the function f(x) is defined.
Now, as the given function f(x) is defined for all the real values of x.
Domain of the function f(x) = cos x : ( - infinity , + infinity)
Hence, Domain : ( -∞ , +∞ )
Also, the graph of the given function f(x) = cos x is attached below :
Now, form the graph also we can see the graph of given function f(x) = cos x can attain all the real values starting from -infinity to +infinity
Answer:
a₁₅ = 71
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 6 - 1 = 5 , then
a₁₅ = 1 + (14 × 5) = 1 + 70 = 71
