The value of (f· g)(x) from the given functions is 3x³+15x.
The given functions are f(x)=x²+5 and g(x)=3x.
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)
= (x²+5) × (3x)
= 3x³+15x
(g·f)(x)= g(x) × f(x)
= (3x) × (x²+5)
= 3x³+15x
Therefore, the value of (f· g)(x) from the given functions is 3x³+15x.
