2.12/25=0.08
5.09/72=0.07
Brand B is the better buy. It is cheaper per unit.
Answer:
The degree is even and the leading coefficient is negative.
Step-by-step explanation:
Given that the end behavior of the function is decreasing on the right, this means that x approaches positive infinity as y approaches negative infinity, which tells us that our leading coefficient is negative. Additionally, since our function is increasing on the left, then our function is even, which is symmetric to the origin.
Well.. I'm not sure if I remember this correctly but doesn't "i" represent the square root of -1? Therefore if you square a square root, they cancel out and you're left with -1 as your answer.
Steps would be to:
change "i" to the square root of -1
put the exponent 2 outside of that
cancel the square root and the exponent
answer= -1
