If it were written in a book of some sort, fx or f(x) is read aloud as "f or x". "f" is a function of some variable, "x". By function it means something happens to x e.g. x2 or 3x+4.
the graph is moved down 6 units
It is the straight line through the points (0, -1) and (1, 0).

Select a set of values for x. For each value of x calculate the corresponding value of y using the function x2 - 4x - 4. Plot these points and join together with as smooth a curve as you can manage.
The graph of the function f(x) = 4, is the horizontal line to the x=axis, which passes through (0, 4). The domain of f is all real numbers, and the range is 4.

the function (x),sory I can`t use the sign of the function because it is not available. the function of (x)=4x+4 is one to one function assume function(x1)= function(x2) then 4(x1)+4 =4(x2)+4 4(x1)=4(x2) (x1)=(x2) hence,the function is one to one

Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.

y = x2 + 4 The graph is a parabola, with its nose at y=4 on the y-axis, and opening upward.
If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.

y = x2 - 4x + 4The 'y-intercept' is the place where the graph of the function lies on the y-axis.But that's just the place where x=0. So all you have to do to find it is set x=0.Y = x2 - 4x + 4Y = 4 when x = 0.The y-intercept is y=4
