Question
Choose all functions that are in family of Trigonometric Functions Group of answer choicesf(x)= 2 cos (x) +5f(x)= 2 / x +5f(x)= sin (x) -3f(x)= 3x2 f(x)= 4sin -9
Solution
The functions that belong to the family of Trigonometric Functions are:
- f(x)= 2 cos (x) +5
- f(x)= sin (x) -3
- f(x)= 4sin -9
The other functions do not belong to the Trigonometric Functions family. The function f(x)= 2 / x +5 is a rational function and f(x)= 3x^2 is a polynomial function.
