Topic 2 Functions

• y = 4/x + 3

• y = (x - 3) / 4

• y = (x + 3) / 4

• y = (x + 4) / 3

• V = 5πr³

• V = 5πr²

• V = 10πr³

• V = 10πr

• V = 4x³ - 90x² + 450x

• V = 2x³ - 90x² + 450x

• V = 6x³ - 90x² - 450x

• V = 4x³ + 90x² + 450x

• A = 4, D = 1

• A = -4, D = 1

• A = 1, D = 5

• A = 1, D = 4

Find f(x) - g(x)

• 2x² + 8x - 8

• 3x² + 8x - 8

• 2x² + 8x + 8

• 2x² + 4x - 8

Find f(x) - g(x)

• x² - 7x + 2

• -x² + 7x + 2

• -x² - 7x + 2

• -x² - 7x + 4

Answer explanation

To find g(x) - h(x), we need to subtract the functions. If g(x) = 3x and h(x) = 8, then g(x) - h(x) = 3x - 8, which matches the correct answer choice.
