Given that f(x) = x2 + 4x – 21 and g(x) = x - 3, find f(x) · g(x) and

Answer:

(f·g)(x) = x^3 +x^2 -33x +63

Step-by-step explanation:

The product of the two functions can be found using the distributive property.

$f(x)\cdot g(x)=(x^2+4x-21)\cdot(x-3)\\\\=(x^2+4x-21)(x)+(x^2+4x-21)(-3)\\\\=x^3+4x^2-21x-3x^2-12x+63\\\\\boxed{(f\cdot g)(x)=x^3 +x^2-33x+63}$

Let f(x) = -20x2 + 14x + 12 and g(x) = 5x - 6. Find f/g and state its domain.

Tanya [424]

Answer: (f/g)(x) = -4x - 2

D: x ≠ 6/5

<u>Step-by-step explanation:</u>

$\dfrac{f(x)}{g(x)}=\dfrac{-20x^2-14x+12}{5x-6}\\\\\\.\qquad =\dfrac{-2(2x+1)(5x-6)}{5x-6}\\\\\\.\qquad =-2(2x+1)\\\\\\.\qquad =-4x-2$

$Domain: \text{denominator cannot be equal to zero}\\\\5x-6\neq 0\\\\5x\quad \neq 6\\\\x\quad \neq \dfrac{6}{5}$
