a) (f+g)(x) = f(x) + g(x) = -4x + 5x = x

b) -9(x) = -9x? I have no idea what this means.

c) (f o g)(x) = (f(g(x)) = f(5x) = -4 (5x) = -20x

Answer:

Calculate the square root of 10 ( ) to 2 decimal places.

Find the two perfect square numbers it lies between. Solution: 32 = 9 and 42 = 16, so lies between 3 and 4.

Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)

Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.
