Is fx -x2 a function?
f(x) = -x2 is a function. The equation is solved with just f(x) on one side, and if you were to graph it, it would pass the vertical line test.
Function notation fx is read as?
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.
Is x2 - 4x -12 prim?
No. x2 -4x - 12 = (x + 2)(x - 6)
Solve x2 - 4x - 9 equals 0 by completing the square?
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13
Factor x2 plus 4x plus 6?
x2 + 4x + 6 can not be factored. If you want, you can reduce it to an expression with a single x term by comleting the square: x2 + 4x + 6 = x2 + 4x + 4 + 2 = (x + 2)2 + 2
What is 4x-x2?
4x-x2 = 2
Is fx -x2 a function?
f(x) = -x2 is a function. The equation is solved with just f(x) on one side, and if you were to graph it, it would pass the vertical line test.
Which statement best describes the function below fx equals x3-x2-9x 9?
A cubic.
What is X2 divided by -4x?
6
Define one-to-one function?
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
What are the factors of x2 - 4x?
-2

Factor x2 - 4x - 32?
x2 - 4x - 32 = (x - 8)(x + 4)
Is x2 - 4x -12 prim?
No. x2 -4x - 12 = (x + 2)(x - 6)
Solve x2 - 4x - 9 equals 0 by completing the square?

What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
