Put f(x) = 0 and solve for x.
Not enough information has been given to determine the value of x
The function that is given has a constant value and therefore, its slope is 0.
A graph is represents a function if for every value x, there is at most one value of y = f(x).
If the equation is of the form y = f(x) where f is some function of the variable x, then The initial value is found by evaluation f(0): that is, the value of f(x) when x = 0. The rate of change is the derivative of f(x) with respect to x, written as f'(x). That is the limit (if it exists), as dx tends to 0, of [f(x+dx) - f(x)]/dx. In the simple case, where f(x) is a linear equation of the form y = mx + c, then f(0) = c and f'(x) = m

You use the inverse function (if one exists).So, if y = f(x) then x = f-1(y)
A function f(x), of a variable x, is said to have a limiting value of f(xo) as x approaches x0 if, given any value of epsilon, however small, it is possible to find a value delta such that |f(x) - f(x0)| < epsilon for all x such that |x - x0| < delta.The second inequality can be one-sided.
A function f(x) is Even, if f(x) = f(-x) Odd, if f(x) = -f(-x)
Given a function f(x) find any anti-derivative, F(x). The set of all possible derivatives is obtained by adding a term not involving x which can take any value. So F(x) + C is a general derivative, where C can take any value.
Given f(x) = 8x + 5 So f(8) = 8 * 8 - 5 = 64 - 5 = 59
If you are talking about a function in a variable (lets say f(x)=1/x) then it probably means that as x gets bigger and bigger, the function f(x) starts to settle around a certain number, ie: f(x) is the same for two really big numbers that are different. With f(x)=1/x we have f(1000000)=1/1000000=0.000001 and f(2000000)=1/2000000=0.0000005 Which are both VERY, VERY close to 0. SO in this example the expression (f(x)=1/x) is approaching a given value of 0.
