ANSWER

The graph of f(x) is horizontally stretched.

EXPLANATION

The given function is

f(x) =  -  \frac{2}{3}  |x + 4|  - 6

The vertex of this function is (-4,-6)

The factor ⅔ strectches the graph horizontally in the graph of f(x) opens wider than the parent function

y=|x|

The negative factor will make the graph open downwards. It is a reflection in the x-axis.

The domain of the graph is all real numbers.

Answer: Second Option

The graph of f(x) is horizontally stretched.

Step-by-step explanation:

We have the function:

f(x) = -\frac{2}{3}|x+4| - 6

The main function y=|x| has its vertex in the point (0,0) opens upwards and its domain is all real numbers.

Notice that f(x) = -\frac{2}{3}|x+4| - 6 is a transformation of the function y=|x|.

Observe the attached image. Where the red line represents the transformed function. Notice that it opens down and is stretched horizontally. Its vertex is at point (4, -6) and the domain is all real numbers

Therefore the statement that is true is the second

The graph of f(x) is horizontally stretched.

Hitman42 [59]

Answer:

tan a + cot b

Step-by-step explanation:

It's already simplified.

There are alternate forms like

sec(a)csc(b)cos(a-b)\\\\sec(a)csc(b)[sin(a)sin(b)+cos(a)cos(b)]\\\\\frac{sin (a)}{cos (a)} +\frac{cos(b)}{sin(b)}
