f(x) = 4x and g(x) = 3x
(fog)(x)
you need take value of g(x), 3x, and put 3x instead of x in f(x) function
(fog)(x)=4*(3x)=12x
f(x) = 4x and g(x) = 3x
(fog)(x)
you need take value of g(x), 3x, and put 3x instead of x in f(x) function
(fog)(x)=4*(3x)=12x
The pairs of function which match to the (fog)(x)=12x will be the f(x) = 4x and g(x) = 3x so last option will be correct.
What is a function?
A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
In question, in option 4 the work or function f is to multiply it by 4
so fg(x) = multiplied by 4 of g(x)
(fog) = 4 × 3x = 12x so it will be correct answer.
