Answer:
The slope is negative
Step-by-step explanation:
If the line is pointing down then the slope is negative. And if the line is pointing up then the slope is positive.
The value of (f· g)(x) from the given functions is
.
The given functions are f(x)=x³+x+1 and g(x)=-x.
<h3>What is the function?</h3>
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](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
(g·f)(x)= g(x) × f(x)
= (-x) × (x³+x+1)
= ![-x^4-x^2-x](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
Therefore, the value of (f· g)(x) from the given functions is
.
