Answer with step-by-step explanation:
Let us find the perfect cubes between 1 to 100.
We know that, 1
3
=1,2
3
=8,3
3
=27,4
3
=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.
So, only these four numbers have their cubes between 1 to 100.
Thus, there are 4 perfect cubes from 1 to 100.
Now, let's find the cubes between −100 to 0
We know, 0
3
=0,(−1)
3
=−1,(−2)
3
=−8,(−3)
3
=−27,(−4)
3
=−64 and the rest numbers have their cubes less than −100
So, only these 5 numbers have their cubes between −100 to 0 and 4 perfect cubes are there from 1 to 100.
Thus, there are 9 perfect cubes from −100 to 100.

Answer:
Step-by-step explanation:
No solution
The graph (by some miracle) has been uploaded for you. It is just about the first time I've done this sort of thing, and I've answered nearly 800 questions.
The first thing you have to do is study the graph. The two functions are
f(x) = 4^x That's the curved graph. (in red)
g(x) = x + 4. That's the straight line. (in blue)
You know that the first one is not a linear relationship because the x values go from integer values -2 to 2 (including 0). The y values are a bit different. They go from 1/16 to 16 with those integer values. So you could try y = 4^(-x). It doesn't work, but you could try it. It gives the table numbers for y in the reverse order that the table you are given goes. For x you get -2 -1 0 1 2 and for y you would get 16 4 1 1/4 1/16.
You could try y = (1/4)^x
For this try, you would get x = -2 -1 0 1 2 and for y = 16 4 0 1/4 and 1/16
but that doesn't work either.
You could try until you get y = 4^x which does work.
g(x) is a lot easier to deal with. It looks better behaved. as x goes up, so does y. You will find that the y values obey y = x + 4. You could try other lines, but that one works. Many times it's just a guess
