Answer:
b. ![\sqrt[3]{4x+2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4x%2B2%7D)
Step-by-step explanation:
f(x) = ( x^3-2) /4
y = ( x^3-2) /4
Exchange x and y
x = ( y^3-2) /4
solve for y
Multiply each side by 4
4x = 4( y^3-2) /4
4x = y^3 -2
Add 2 to each side
4x+2 = y^3
Take the cubed root of each side
( 4x+2) ^ (1/3) = y^3 ^(1/3)
( 4x+2) ^ (1/3) =y
Let's look at the possibilities:
1. Reflection along the y-axis and rotation of 180 degrees by the origin 0. (Gives us 4 and then 2 in the end)
2. Reflection along the y-axis and reflection along the x-axis. (Gives us 4 and then 3 in the end)
3. Reflection along the x-axis and rotation 90 degrees by the origin 0. (Gives us 4 and then 1 in the end)
4. Rotation of 270 degrees by the origin 0. (Gives us 2 in the end)
Option 2 is the answer.
Best of luck!
Answer:
Step-by-step explanation:
With this question, we just have to group the terms, so in this case, we can remove the common term (x - 4), and then group the rest of them
If we do that we get:
(x - 4) (2x + 7)
Hope this helps,

For this case we have the following expression:
(6.21 + 0.93) + 0.07
We apply the associative property of the addition to rewrite the expression.
This property indicates that, when there are three or more terms in these operations, the result does not depend on the way in which the terms are grouped.
We have then:
6.21 + (0.93 + 0.07)
Answer:
6.21 + (0.93 + 0.07)
Associative property.
