Answer:

A quadratic equation

Step-by-step explanation:

f(x) = (x + 3)(x - 7) \\ f(x) =  {x}^{2}  - 7x + 3x - 21 \\ f(x) =  {x}^{2}  - 4x - 21

Novay_Z [31]

Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20

Which of these statements best describes the relation shown in Item 1?
Misha Larkins [42]

Answer:

It is a many-to-one relation

Step-by-step explanation:

Given

See attachment for relation

Required

What type of function is it?

The relation can be represented as:

\left[\begin{array}{c}x\\ \\-5\\-2\\1\\5\end{array}\right]         \left[\begin{array}{c}y\\ \\10\\11\\4\\10\end{array}\right]

Where

x = domain and y = range

Notice that the range has an occurrence of 10 (twice)

i.e.

(x_1,y_1) = (-5,10) and (x_2,y_2) = (5,10)

In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
