ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if

Thus, the function is one to one.
For y=x or


Hence this function has an inverse.
For the function y=x² or f(x)=x².

This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³

This function also has an inverse.
For y=x⁴ or f(x) =x⁴

This function has no inverse over the entire real numbers.
Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.
≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
Answer:
red,because The probability of choosing red is 5/12 but this probability for purple and blue is 2/12=1/6,and also for green marbles is 3/12=1/4
5/12>3/12>2/12
Yes, the partition gives the two brothers equal shares.
Step-by-step explanation:
Step 1:
Assume the entire field has an area of B. So one brother takes
,
, and
So we need to calculate how much this brother takes in terms of B.
To do this we calculate how much
is.
Step 2:
To add
,
First take the LCM of the denominators 12, 6, and 4
The LCM is 12, we multiply the denominator to get the LCM value, this same value is multiplied to the numerator too.

Step 3:
One brother gets
, so we need to calculate how much the other brother gets.
The other brother's share = 
So both the brothers get equal shares
