Answer:

The answer is the option D

$21x^{2}+32x+12$ ; All real numbers

Step-by-step explanation:

we have

$f(x) = 3x + 2$

$g(x) =7x + 6$

Calculate f(x)*g(x)

$(3x + 2)*(7x+6)$

Multiply applying the distributive property

$(3x + 2)*(7x+6)=3x*7x+3x*6+2*7x+2*6\\=21x^{2}+18x+14x+12\\=21x^{2}+32x+12$

The domain of the function is the interval------> (-∞,∞)

Help!! I cant figure this out for some reason

Thepotemich [5.8K]

Answer:

x³ - 6x² + 18x - 10

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

= x³ - 2x² + 12x - 6 - (4x² - 6x + 4)

= x³ - 2x² + 12x - 6 - 4x² + 6x - 4 ← collect like terms

= x³ - 6x² + 18x - 10
