Function Operations: Adding, Subtracting, Multiplying

Given

f(x) = 3x² + 7x and g(x) = 2x² - x - 1, find f(x) + g(x).

• 11x² - 1

• 5x⁴ + 6x² - 1

• 5x² + 6x - 1

• 5x² + 8x - 1

f(x) = 3x² + 7x and g(x) = 2x² - x - 1, find f(x) - g(x).

• x² + 8x + 1

• x² + 6x - 1

• 5x² + 8x - 1

• x² + 8x -1

Given f(x) = 3x² - 2x + 1 and g(x) = x - 4, find f(x) * g(x).

• 3x³ - 10x² - 7x - 4

• 3x³ - 14x² + 9x - 4

• 3x² - x - 3

• 3x³ + 14x² - 9x - 4

• Function
• Not a Function

f(x) = 6x² + 3x + 2 and g(x) = x - 7

Find f(x) * g(x)

• 6x³ - 39x² - 19x + 14

• 6x³ - 39x² - 21x - 14

• 6x³ - 39x² - 19x - 14

• 6x³ - 45x² - 19x + 14
