Let f(x) = x2 – 16 and g(x) = x + 4. Find fg f g and its domain.

Marta_Voda [28]

Answer: fg $=x^3+4x^2-16x-64$ and

Domain: All real number. All real number or $(-\infty,\infty)$

Explanation:

fg means product of two given function f(x) and g(x)

where,

$f(x)=x^2-16$ and $g(x)=x+4$

Now, we have to find fg

So, fg= $f(x)\times g(x)$

Substitute f(x) and f(x)

$\Rightarrow (x^2-16)(x+4)$

Using distributive property simplify above expression and we get,

$\Rightarrow x^3+4x^2-16x-64$

We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.

Domain: All real number or $(-\infty,\infty)$
