You must provide a complete equation for the function. Do you mean f(x) = 1.5x + 7.6 or something else?
If you mean: x-2y = 8 then it is y = 0.5x-4.
The expression fxfxf means f(f(x)f(x)), where f(x) is a function of x. This is not equivalent to f cubed (f^3(x)), which would mean f(f(f(x))). In fxfxf, the function f(x) is applied twice to the input x, whereas in f cubed, the function is applied three times. The two expressions are different due to the number of times the function is applied to the input.
f(x) = ...f is the name of the function, and x is the variable. I guess you could say x is the root of the function, because it is what the function relies on.
The only function that can be symmetric about the x-axis is the x-axis itself. For each value of x a function, f(x), can have at most one value for f(x). Otherwise it is a mapping or relationship but not a function.
If you mean x + y = 18 then it is the function of a straight line
It depends on how you mean, e.g. if you mean that the function which takes a number x to 5141312111 times x, then yes, it is linear, and is trivial to show.
It means that the value of the function at any point "x" is the same as the value of the function at the negative of "x". The graph of the function is thus symmetrical around the y-axis. Examples of such functions are the absolute value, the cosine function, and the function defined by y = x2.
Whenever you see a function such as the sine function, you have to see the function as a whole. The "s" doesn't mean anything by itself in this case; sin(x) means the sine of an angle x.
It means that there is no linear relationship between the argument of the function, x, and the functional value, f(x) or y.
Yes, y =5 is a constant function. Meaning that for any value of x (in the domain), the value of the function (y) is 5. The graph would be a horizontal line five units above, but parallel to, the x-axis. Another answer: The above comments are only valid if we specify that x is just some constant. In general, however, when we refer to the function y=f(x)=x we do not mean a constant function, but rather a diagonal line running through the origin. The function would be a constant function if it were y=f(x)=c for some c, but normally when we write y=x we mean that the value of y is the value of x, and hence y changes as x changes.
Yes, h(x) is simply a function h --> x, like f(x) is a function f --> x. The different letters are used to illustrate the fact that the two functions need not be the same.
You must provide a complete equation for the function. Do you mean f(x) = 1.5x + 7.6 or something else?
Yes, if your equation is f(x) = sqrt5(x). The square root is also a function itself, if that's what you mean.
The word non-function can mean practically anything, a variable, for example.int fun (int x) { return x+10; }int nonfun= 32;
For a function of only one variable it mean the derivative with respect to that variable. Thus, f'(x) = df(x)/dx. Occasionally, it can also refer to a variation of a function. For example, a family of functions, f(x), f'(x), f''(x) and so on.
You mean the byte-order? x=((x>>8)&0xff) | ((x&0xff)<<8);
