What is the factorization of the polynomial below<br>-x^2 - 15x - 56

Andrej [43]

Answer:

Step-by-step explanation:

This is more easily understood if you take out a common factor of -1

-1(x^2 + 15x + 56)

7*8 = 56

7 + 8 = 56

-1 (x +8)(x+7)

If the function f(x) = (2x - 3)2 is transformed to g(x) = (-2x - 3), which type of transformation occurred?

san4es73 [151]

Answer:

A. horizontal reflection

Step-by-step explanation:

Given:

$f(x)=(2x-3)^2$

$g(x)=(-2x-3)^2$

To identify the type of transformation.

Solution:

On close observation of the functions we find the that sign of $x$ has changed in $g(x)$ with other terms being constant.

<em>Thus, the transformation statement can be given as:</em>

$f(x)\rightarrow f(-x)$

As:

$f(x)=(2x-3)^2$

$f(-x)=(2(-x)-3)^2= (-2x-3)^2 = g(x)$

The transformation $f(x)\rightarrow f(-x)$ describes horizontal reflection of function across the y-axis.

Thus, $f(x)$ is horizontally reflected across y-axis to get $g(x)$ .
