The best way to approach this problem is to start off by doing factor by grouping.
Rectangle definitely not a parallelogram
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
<span>Twice a number is equal to negative four :
2n = -4
answer
</span><span>2n = -4
last one is your answer</span>
To find volume, we will use the following equation: V=4/3piR^3
The correct answer should be 1436.76
