Answer:

f(x) = x² - 9

Step-by-step explanation:

Given x = a is a zero of the polynomial f(x) then (x - a) is a factor

Given zeros are x = 3 and x = - 3, then corresponding factors are

(x - 3) and (x - (- 3) ), that is

(x - 3) and (x + 3)

The function is then the product of the factors, that is

f(x) = (x - 3)(x + 3) ← expand using FOIL

f(x) = x² - 9

Svetlanka [38]

The range will be all ur y values...just as the domain is all the x values

so ur range is {5,6 }...notice that even though they repeat, u only have to list them once

Which of the following is a solution of y - x < -3?

Mariulka [41]

Answer:

Option A. (6,2)

Step-by-step explanation:

We have the following inequality:

$y- x$

Solving for y we have:

$y$

The line that limits the region of inequality is

$y = x-3$

Then the region of inequality are all values of y that are less than $f (x) = x-3$

In other words, the points belonging to the inequality are all those that lie below the line.

To find out which point belongs to this region substitute inequality and observe if it is satisfied

A. (6,2)

$2$

$2$ is satisfied

B. (2, 6)

$6$

$6$ it is not satisfied

C. (2, -1)

$-1$

$-1$ it is not satisfied

The answer is the option A

In the function y = 15.00x + 5, y represents the cost of a ticket to the fair and x represents the number of tickets purchased.

kkurt [141]

For every ticket purchased, the cost will increase by $15.00 because x indicates that $15 is the unit rate for each ticket.
