QUESTION 1a.

We want to add

( - 2 {x}^{2}  - 4x + 13) + (12 {x}^{2}  + 2x - 25)

We group similar terms to get

- 2 {x}^{2}  + 12 {x}^{2}- 4x + 2x   - 25 + 13

Simplify:

- 10{x}^{2} - 2x  -12

QUESTION 1b.

The given function is:

(7x^2+4x-26)-(-7x^2-3x+15)

Expand the parenthesis to obtain,

7x^2+4x-26 + 7x^2 + 3x - 15

Group similar terms,

7x^2+7 {x}^{2}  + 4x + 3x-26  - 15

Simplify:

14{x}^{2}  + 7x-41

QUESTION 2

The given function is

f(n)=n^2-6n-16

The zeros of this function is given by;

n^2-6n-16 = 0

Split the middle term.

n^2-8n + 2n-16 = 0

Factor;

n(n - 8) + 2(n - 8) = 0

(n - 8)(n + 2) = 0

n - 8 = 0 \: or \: n + 2 = 0

n  = 8 \: or \: n =  - 2

Answer:

y = 3x - 1

Step-by-step explanation

We manipulate the scatter plot feature in Ms. Excel then we simply add the linear trend line displaying the equation on the chart.

The excel output is attached below.

The relation exhibited by the data set is y = 3x - 1; given the value of x, the value of y is obtained by multiplying x by 3 and subtracting 1 from the result.
