Answer:

1. are you serious to ask ? it is written right there in the question itself. x=0, f(0)=y=6

2. the slope is 3

3. -4/3

4. $1.50 per book

5. -2

Explanation:

1. the table itself says it for x=0. f(x) for x=0 is 6.

2. as explained do often already. the slope is the ratio of y/x showing how many units y changes, when x changes a unit or another surviving number of units.

the table shows when x increases by 1 unit, y increases by 3 units. so, the slow is 3/1 or simply 3.

3. again slope (see 2.).

going from M to N x increases by 4 units (from 1 to 5), and y decreases by 3 units (from 3 to 0).

so, the slope is y changes / x change = 4/-3 or simply -4/3

4. rate of change is

(f(a) - f(b)) / (a - b)

e.g.

(275 - 50) / (250 - 100) = 225 / 150 = 1.5

5. again very simple. which of the provided answer options appears in the f(x) column ?

the result of a function is the functional or y value calculated by the formula when responding the generic variable (like x) by the specified input value.
