If fx equals x2 then fx-1 equals?
3
What is the answer to F times x equals x squared minus 3?
Are you trying to solve for x? Fx = x2 - 3 x2 - Fx - 3 = 0 x2 - Fx = 3 x2 - Fx + (F/2)2 = 3 + (F/2)2 (x - F/2)2 = 3 + (F/2)2 x - F/2 = ±[ 3 + (F/2)2 ]1/2 x = F/2 ± [ 3 + (F/2)2 ]1/2
What is xf compared to fx How are they different?
If x and f are quantities then xf and fx are the same if they belong to a commutative space. If not, they normally do not. Multiplication of matrices, for example is cont commutative. In fact, it is quite possible that xf has a value but fx does not even exist. if x and f are functions then again, fx and xf will not generally be the same. For example suppose x = "add 5 to it" and f = "square it". Then xf(3) = x(9) = 14 while fx(3) = f(8) = 64
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.
If fx equals 3x-5 then f2 equals?
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
