The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be. I can only see f(x plus 1) 2x 1. I can see that it is means to be f(x+1) = 2x ~ 1but the ~ remains an unidentified operator.
From the above, you can deduce that f(x) = 2(x - 1) ~1 = 2x - 2 ~1
Similarly g(x) = 4x - 4 + 4 = 4x.
Then f(g(x) = f(4x) = 2*4x - 2 ~ 1 = 8x - 2 ~ 1.
You will need to substitute the appropriate operator for ~ and evaluate.

What is the derivative of fx where fx equals 2x-3 all under square root?
f(x) = √(2x -3) f(x) = (2x - 3)^(1/2) f'(x) = (1/2)[(2x - 3)^(1/2 - 1)](2) f'(x) = (2x - 3)^(-1/2) f'(x) = 1/[(2x - 3)^(1/2)] f'(x) = 1/√(2x -3)
Use the the following functions to solve fx x2 x 1 gx 5 - 2x hx -x2 goh2?

What is the range of fx equals 2x - 5?
Domain is the number of x values that can be used and not cause an imaginary result. Range is the number of the y values that result. In f(x)=2x-5 the range is all real numbers.
If hx equals f o g x and hx equals sqrt x plus 5 find gx if fx equals sqrt x plus 2?
g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)
In the function G Fx G depends on F and F depends on x?
true
Fx equals 3 plus 4x?
y = 3x + 2x^2 + k where k is any number
Fx 2x plus 1 over x squared minus 2x minus 8?

When gx and fgx are known how do you find fx where fx gx are functions of x and fgx is a function of gx?
Since g(x) is known, it helps a lot to find f(x). f(g(x)) is a new function composed by substituting x in f with g(x). For example, if g(x) = 2x + 1 and f(g(x)) = 4x2+ 4x + 1 then you you recognize that this is the square of the binomial 2x + 1, so that f(g(x)) = (f o g)(x) = h(x) = (2x + 1)2, meaning that f(x) = x2. if you have a specific example, it will be nice, because there are different ways (based on observation and intuition) to decompose a function and write it as a composite of two other functions.
Fx equals -2x plus 4 divided by 3x-5?
please elaborate your question
What is the derivative of fx equals x to the power of 2 over x plus 2?
That is the quotient rule and your function is.... f(x) = X^2/x+2 = (x+2)*2x-x^2*1/(x+2)^2 = 2x^2+4x-x^2/(x+2)^2 = x^2 + 4x/(x+2)^2
Fx equals x cubed plus 4?
x = ¼x^4 + 4x + k where k can be any number
Let fx x2 and gx 3x 8 Determine all values of x such that fgx gfx?
The values of x such as fgx= gfx is math. It comes down to finding the value of the letter X.
If fx -2x 1 and gx -4x then gf4?
f(x) = -2x + 1; g(x) = -4x; g(f(4)) = ? Solution: (g ° f)(4) = g(f(4)) = g(-7) = 28 f(x) = -2x + 1 f(4) = -2(4) + 1 f(4) = -7 g(x) = -4x g(-7) = -4(-7) g(-7) = 28
If fx 4x - 6 what is f-3?
