The function has a domain of all real numbers . True
<em>The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.</em>
The function is a reflection of y =³√x . True
The function is always increasing. False
<em>When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.</em>
The function has a range of {y|– < y < } . False
The function passes through the point (3, –27) . False
<em>When this values are substituted it the function they don't satisfy it. </em>
The answer is 5. You are basically adding a 2 to the 3 which means you’ll get 5
The total number of elements in either Set A or Set B. is 124.
<h3>How can the number of
set in mathematics be calculated?</h3>
Since Set A contains 62 elements
Set B contains 94 elements
Then total element= (62+94)=156
But the Sets A and B have 32 elements
Therefore, total number of elements in either Set A or Set B. is (156-32)= 124.

Answer: C. Package 3
First, find out what each cell phone package costs for 1 month by dividing the cost by however many months:
Package 1: $160 ÷ 4 = $40 for 1 month
Package 2: $128 ÷ 4 = $32 for 1 month
Package 3: $60 ÷ 2 = $30 for 1 month
Since package 3 costs the least amount of money for 1 month out of all of the other packages, that package offers the best deal. So C) Package 3 is your answer
3.4+0.5y +1.1=-4.5
3.4+1.1+0.5y= -4.5
4.5+0.5y=-4.5
move 4.5 to the other side
sign changes from +4.5 to -4.5
4.5-4.5+0.5y= -4.5-4.5
0.5y= -4.5-4.5
0.5y=-9
divide both sides by 0.5
0.5y/0.5= -9/0.5
Answer: y= -18
