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.
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.
Is x the numbers that are domains of both f and g in the function fgx?
No. The set of x-values are the domain for only g. This will result in a set of images, which will be g(x). This set of g(x) values are the domain of f.
Why do you find median?
You find the median to find the middle number
How do you find the base of the base shape to find the volume?
You find the length and height of the shape, them you find the volume
