ANSWER

Given

r(x) = x - 1


and

s(x) = 3 {x}^{2}
ANSWER TO QUESTION 1

(r + s)(x) = r(x) + s(x)


(r + s)(x) = x - 1 + 3 {x}^{2}


(r + s)(x) =  3 {x}^{2}  + x - 1



ANSWER TO QUESTION 2



(r \times s)(x) = r(x) \times s(x)


(r \times s)(x) = (x - 1) \times 3 {x}^{2}


(r \times s)(x) = 3 {x}^{3}  - 3 {x}^{2}

ANSWER TO QUESTION 3

( r - s)(x) = r(x) - s(x)



( r - s)(x) = x - 1 - 3 {x}^{2}


( r - s)( - 3) =  (- 3) - 1 - 3 ({ - 3}^{2} )



( r - s)( - 3) =   - 4 - 3  \times 9



( r - s)( - 3) =   - 4 - 27 =  - 31

The stock of Company A gained $0.18 throughout the day and ended at a value of $6.18. By what percentage did the stock rise
erastovalidia [21]

Answer: % increase ≈ 3433%

Step-by-step explanation:

Step 1: work out the difference (increase) between the tow numbers you are comparing.

Increase = New Number - Original Number

Step 2: Divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number x 100

Step 3: Plug in known values

Increase = 6.18

Original Number = 0.18

% increase = 6.18 ÷ 0.18 x 100

% increase = 34.333... x 100

% increase ≈ 3433%
