Let f ( ) sin(arctan ) x x = . What is the range of f ?
nikklg [1K]
<span>So you have composed two functions,
</span><span>h(x)=sin(x) and g(x)=arctan(x)</span>
<span>→f=h∘g</span><span>
meaning
</span><span>f(x)=h(g(x))</span>
<span>g:R→<span>[<span>−1;1</span>]</span></span>
<span>h:R→[−<span>π2</span>;<span>π2</span>]</span><span>
And since
</span><span>[−1;1]∈R→f is defined ∀x∈R</span><span>

And since arctan(x) is strictly increasing and continuous in [-1;1] ,
</span><span>h(g(]−∞;∞[))=h([−1;1])=[arctan(−1);arctan(1)]</span><span>
Meaning
</span><span>f:R→[arctan(−1);arctan(1)]=[−<span>π4</span>;<span>π4</span>]</span><span>
so there's your domain</span>

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays
Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

x+y\leq20 -----> inequality A

9x+10y\geq 90 -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

<em>Verify</em>

For (10,10)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

10+10\leq20

20\leq20  -----> is true

<em>Inequality B</em>

9(10)+10(10)\geq 90

190\geq 90 ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

<em>Inequality A</em>

0+9\leq20

9\leq20  -----> is true

<em>Inequality B</em>

9(0)+10(9)\geq 90

90\geq 90 ----> is true

therefore

(0,9) is a possible solution
