Given

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

• 4x² - 1

• 4x³-1

• 3x² + x - 1

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

• 3x^{2 -} (x-1) = 3x²-x+1

• x-1-3x² = -3x²+x-1

g(x)=3x²

f(x)= x-1

Find (g*f)(x)

• 3x³ - 3

• 3x³ - x²

• 3x³ - 3x²

f(x) = 3x²

g(x) = x - 1

Find (f o g)(x).

• 3x² - 3

• x² -2x + 1

• 3x² -6x + 3

• None of these.

f(x) = 3x + 10

g(x) = x - 2

Find (f o g)(0).

• 16

• 4

• -4

• None of these.

What is the inverse of the given coordinates: (1, 2) (3, 8) (-3, 6)

• (1, 2) (3, 8) (-3, 6)

• (2, 1) (8, 3) (6, -3)

• (-1, -2) (-3, -8) (3, -6)

Are the following inverses of each other?

• True
• False
