Question

If f(x)=x³+x+1 and g(x)=-x, find (f°g)(x) and (g°f)(x). (f°g)(x)=

Answer 1

The value of (f· g)(x) from the given functions is $-x^4-x^2-x$.

The given functions are f(x)=x³+x+1 and g(x)=-x.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Here,

(f·g)(x)= f(x) × g(x)

= (x³+x+1) × (-x)

= $-x^4-x^2-x$

(g·f)(x)= g(x) × f(x)

= (-x) × (x³+x+1)

= $-x^4-x^2-x$

Therefore, the value of (f· g)(x) from the given functions is $-x^4-x^2-x$.
