For every one pound she paid 2.44 dollars
Answer: (B) x^3
Explanation:
If you compare the graphs of
all on the interval -1 < x < 0, you'll find that y = x^3 is the smallest when x = -1
Squaring a negative number leads to a positive result, and similarly that happens with x^4 as well. This is because x^4 = (x^2)^2.
Plugging x = -1 into x^3 leads to y = -1 as a result.
I am pretty sure it is (a) because 9 and 15 and 3 and 6 can be all divided by 3
The answer is: (x-9)^2+(y+4)^2=92
