The local extrema of f(x) = x + 2*sin(x) are 6.2832 and 2.4567 (approx).If the question was about some other function of x, please resubmit using words for mathematical symbols. The browser that you are required to use for posting questions is rubbish and will reject most mathematical symbols. In this case, all that I can see is "f(x)x 2sinx" and have had to guess the rest.

The mathematical product of 5 and x is 5x.
X is a variable in the mathematical language. X could be any number, letter or equation.
A basic wave function is a sine or cosine function whose amplitude may have a value other than 1. The cosine function is an even function because it is symmetrical about the y-axis. That is, f(-x) = f(x) for all x. The sine function is an odd function because it is antisymmetrical about the y-axis. That is, f(-x) = -f(x) for all x.
Nope.* * * * *The above answer is so wrong!Suppose f and g are two transformations wheref(x) = 2x, andg(x) = x2Then f(g(x)) = f(x2) = 2x2Whileg(f(x)) = g(2x) = (2x)2=4x2Therefore f(g(x)) = g(f(x)) only when x = 0

The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has been changed somewhat. Which of the following could be the equation of F(x)?
The browser used by this site for posting questions is almost totally useless for many mathematical questions because it rejects most mathematical symbols and does recognise superscripts.I am assuming the expression is f(x) = 900*(0.65)^x. If so, the domain is x>= 0.

It is difficult to be sure because the browser used for posting questions on this site is utter rubbish and strips out all mathematical symbols. If your question was f(x) = x + 2 then the inverse is f(x) = x - 2.

F = 32 + C x 1.8 or C = (F - 32) x 5/9 Where F is Fahrenheit and C is Celsius.
It is difficult to tell what function you have in the question because the browser used by this site is hopelessly inadequate for mathematical notation.However,f(x) is an odd function of x if and only if f(-x) = -f(x) for all x.Common examples are f(x) = x^k where k is any odd integer, f(x) = sin(x).
Yes, a constant function has degree 0; i.e., f(x)= a where a does not equal 0 is a mathematical function of degree 0. Lowell F. Lynde, Jr. (Univ. of Arkansas at Monticello)
Function notation means the function whose input is x. The mathematical way to write a function notation is f(x).
The expression "f(x) = y" represents a mathematical function where the variable x is inputted into the function f, and the result or output of the function is represented by y. In this context, "f" is the name or symbol of the function, "x" is the input variable, and "y" is the output or value of the function when x is used as input. The equation implies that the value of y depends on the value of x according to the rules defined by the function f. For example, if we have a function f(x) = 2x + 3, it means that when we substitute a value for x, the function will multiply that value by 2, add 3 to it, and yield the corresponding value of y. So, "f(x) = y" is a mathematical notation that shows the relationship between the input variable x and the corresponding output y through the function f.
