<u>Answer:</u>

The domain and range both are

{x | - ∞ < x < ∞}

<u>Step-by-step explanation:</u>

We know that the x in tan(x) can take any value over real line and

tan(x) → ∞ as x → (π / 2)

and tan(x) → - ∞ as x → - (π / 2)

and tan(x) is strictly monotonically increasing in ( - (π / 2),  (π / 2))

and tan(x) has a period of (π). since,

tan(x + π) = tan x

So the domain and range of tan(x) both are

{x | - ∞ < x < ∞}

stepan [7]

Answer:

B) -3                                 (Sorry if its overwhelming)

Explanation:

First, we have the given information of the weather over a <em>2</em> and <em>1/5</em> <em>span</em>

And we are asked to find the change per hour

We can first start by finding the <em>change</em> for 2 and 1/5 hours:

- Subtract the first amount by the second amount.

= (-6 3/5) - 0

= (-6 3/5) + 0

= -6 3/5

Now that we have the change for <em>2 and 1/5 hours</em> we must find the <em>change</em> per hour:

- Divide the given dividend by the given divisor

= -6 3/5 ÷ 2 1/5

= -3

Hence, the temperature <em>change per hour</em> over a 2 1/5 hour span is -3° per hour

Which equation best represents the graph above
Svet_ta [14]

Answer:

x = -1

Step-by-step explanation:

Since the line is completely vertical there is no slope.

When a line is completely vertical, the setup is x = ___ (fill in the blank with the number that the line intersects on the x axis, in this case -1.)

When a line is completely horizontal (not applicable in this problem) the setup is y = ___ (fill in the blank with the number the line intersects on the y axis.)
