f(x) = 4x+8
g(x) = x+3,
Find f(x)*g(x)

• 4x²+24
• 4x²+20x+24
• 4x²+12x+24
• 4x²+4x+24

f(x)=2x + 4

g(x)=3x² - 1

Find f(x) ⋅ g(x)

• 6x⁴ + 12x³ - 4x² - 8x

• -6x³ + 12x² + 2x - 4

• 6x³ + 12x² - 2x - 4

• 5x² - 18x + 20

If g(x) = 6x + 4 and f(x) = 3, find f(x) * g(x)

• 18x + 4

• 9x + 7

• 6x + 7

• 18x + 12
