The required domain of the inverse function is x ≤ 0. Hence option D is correct.

f(x) = -x^2

<h3>What are functions?</h3>

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.

Inverse of function f(x) = -x^2
y = -x^2
x = √-y
Now,
Inverse function of f(x) is √-x
Its domain is define as less than or equal to zero.

Thus, the required domain of the inverse function is x ≤ 0.

Does anyone know how to do thesubstitution method?

Angelina_Jolie [31]

Hi!

<h3>How do we use the substitution method?</h3>

To solve using the substitution method, we first want to isolate any of the variables from one of two equations, and then you take the value of that and plug it into the other equation.

<h3>Given:</h3><h3> $y=4x-10$ </h3>

$y=-3x+4$

Normally, our step one would be to pick a variable and isolate it, but it looks like we already have the y-value in both equations isolated! So our step one is already done!

Plug the isolated variable into the other equation.

We will use the value of y in the first one, and plug it into the second.

The value of y is "4x - 10", so we will change "y" in the second equation to "4x - 10", like so:

$4x-10=-3x+4$

<h3>Step Three:</h3>

Algebra!

You should be familiar with how to solve equations.

So:

$4x-10=-3x+4$

Add 10 to both sides:

$4x=-3x+14$

Add 3x to both sides:

$7x=14$

Divide both sides by 7:

$x=2$

Now, take the x value and plug it into one of the other equations and solve for y.

$y=4(2)-10$

$y=8-10$

$y=-2$

Therefore, our answer is (2, -2).

Sin x = cos<br><br>I do not understand trig

frez [133]

Answer:

tanx = 1

Step-by-step explanation:

I assume you mean sinx = cosx

In this case we have to recognize that tanx = sinx / cosx

So if we divide cosx over we can get tanx

So:

Cosx divided by itself gives us 1

sinx / cosx = 1

tanx = 1

<u>Answer </u><u>:</u>

This figure consists of two shapes that are a rectangle and a square . We will first find the area of rectangle then the square then add them . Let's work on this together ,

Breadth of rectangle = 4 cm
Length of rectangle = 4 + 5 + 3
Length = 12 cm
Area of rectangle = 12 × 4
48 cm²

Area of square ,

Side × Side
5 × 5
25 cm²

Total area of the figure ,

48 + 25
73 cm²
