Answer:

it's actually none of these.

Step-by-step explanation:

if we divide 15 by 3 we also have to divide 42 by 3. We end up with 5:14. 15 isn't divisible by any number other than 1, 3, 5, and 15.

What transformations change the graph of f(x) to the graph of g(x)?

Dennis_Churaev [7]

For this case we have that the main function is given by:

$f (x) = - 7x ^ 2$

We apply the following transformations:

Vertical expansions:

To graph y = a * f (x)

If a> 1, the graph of y = f (x) is expanded vertically by a factor a.

For a = 5 we have:

$h (x) = 5 * f (x)\\h (x) = 5 * (- 7x ^ 2)\\h (x) = - 35x ^ 2$

Vertical translations:

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

For k = 5 we have:

$g (x) = h (x) + k\\g (x) = - 35x ^ 2 + 5$

Answer:

The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.

Now describe a situation involving area in square feet that can be modeled using the function g(x) = 2x2 − 13x + 6 so that it re

Anna [14]

Answer:

$Length = 2x - 1$

$Width = x - 6$

Step-by-step explanation:

Given

$g(x) = 2x^2 - 13x + 6$

Required

Model as the area

$g(x) = 2x^2 - 13x + 6$

Expand:

$g(x) = 2x^2 - 12x -x+ 6$

Factorize:

$g(x) = 2x(x - 6) -1(x- 6)$

$g(x) = (2x - 1) (x- 6)$

Area is calculated as:

$Area = Length * Width$

So, by comparison:

$Length = 2x - 1$

$Width = x - 6$
