Which statement is true about the function

Lana71 [14]

You solve for the domain by setting the radicand less than or equal to 0 and solving for x. Dividing by a -x, we switch the sign so we have that the domain is less than or equal to 0, or all negative numbers. We know that it breaks every law in math to have a negative radicand with an even index, so if the domain is all negative values of x, taking a negative of a negative gives us a positive. The negative sign OUTSIDE the radical means you are flipping the graph upside down. So instead of having a range of y is greater than or equal to 0 as does the parent graph, you have flipped it upside down so it heads more negative in regards to the range. Therefore, the domain and the range both have the same sign, thee last choice from above.

What is the difference?

worty [1.4K]

Answer:

4th option

Step-by-step explanation:

Given

$\frac{x}{x^2+3x+2}$ - $\frac{1}{(x+2)(x+1)}$ ← expand denominator using FOIL

= $\frac{x}{x^2+3x+2}$ - $\frac{1}{x^2+3x+2}$

Since the denominators are common, then subtract the numerators

= $\frac{x-1}{x^2+3x+2}$

F(x)=x^2-2.g(x)=4x-2

Alex777 [14]

Answer:

Step-by-step explanation:

f(x) = x²-2

g(x) = 4x-2

f.g(x)= x²-2(4x-2) = x²(4x-2)-2(4x-2) = 4x³-2x²-8x+4

f.g(x) = 4x³-2x²-8x+4

The scale on a map is 2 centimeters= 50 kilometres.Two rivers on a map are located 9.3 centimeters apart.What is The actual dist

Yuki888 [10]

Answer:

The actual distance between the two rivers is <u>232.5 kilometers</u>.

Step-by-step explanation:

GIven:

The scale on a map is 2 centimeters= 50 kilometres.Two rivers on a map are located 9.3 centimeters apart.

Now, to find the actual distance between the two rivers.

Let the actual distance between the two rivers is $x.$

The two rivers on the map is located apart of 9.3 centimeters.

According to the scale on the map is 2 centimeters = 50 kilometers.

<em>So, 2 centimeters is equivalent to 50 kilometers.</em>

<em>Thus, 9.3 centimeters is equivalent to </em> $x.$ <em />

Now, to solve by using cross multiplication method:

$\frac{2}{50} =\frac{9.3}{x}$

<em>By cross multiplying we get:</em>

<em /> $2x=465$ <em />

<em>Dividing both sides by 2 we get:</em>

$x=232.5\ kilometers.$

Therefore, the actual distance between the two rivers is 232.5 kilometers.
