If the equation is x/(x^2-4) then I will solve it here
it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff
f(x)=x/(x^2-4)
we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2
so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
Answer:
Correct
Step-by-step explanation: took it on an assignment and got it correct
A=l*w
A=0.35 km*0.3=0.05 km^2
we transform in meters
0.05 km^=50m^2
Answer: the slope of the line is 2/1
Step-by-step explanation:
Find a point on the graph and the go up twice until you see another point on the graph. So go to the right once. So you have found the slope of the line which is 2/1.
