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:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
