Question

If f(x) = 2x +1 and g(x) = -x2,

Answer 1

The value of (f·g)(x) from the given function is -2x³ - x².

The given functions are f(x) = 2x +1 and g(x) = -x².

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)

= (2x +1) × (-x²)

= 2x × (-x²) + 1 × (-x²)

= -2x³ - x²

Therefore, the value of (f·g)(x) from the given function is -2x³ - x².
