Answer 2

It looks like you've provided four different functions, and I'm not sure what you'd like to know about them. If you have specific questions or tasks related to these functions, please let me know, and I'd be happy to assist you. For now, I can provide some general information about each of these functions:

1. f(x) = (3x + 5)

   • This is a linear function, and its graph is a straight line. The slope of the line is 3, and the y-intercept is 5.

2. f(x) = cos(3x)

   • This is a trigonometric function. It represents the cosine of 3 times x. The graph of this function is periodic, with a period of 2π/3. It oscillates between -1 and 1.

3. f(x) = √(5x^2 + 3x)

   • This is a square root function. It involves the square root of a quadratic expression. The graph of this function can be a combination of parabolic and linear segments, depending on the values of x.

4. f(x) = 3x^5 + cos(5x)

   • This is a combination of a polynomial function (5th-degree polynomial) and a trigonometric function (cosine). The graph will exhibit both polynomial and periodic behavior.

If you have specific questions about any of these functions or need to perform certain tasks with them, please provide more details, and I'll be happy to assist you further.
