7 1/2
Or
7.5
That's the answer
Here, Your Expression: y = 0.25 (2^x)
So, we can see the expression is "Exponential" which increases double in every hour. So, the only graph with that pattern is 3rd one.You can compare following coordinates: (1, 50), (2, 100), (3, 200)
For every 1 value of x, y increases to it's double.
In short, Your Answer would be Option C
Hope this helps!
By comparing all the options with the formula of sum of cubes and difference of cubes we get that
is sum of cubes

What is formula of sum of cubes and difference of cubes?</h3>
Formula of sum of cubes and difference of cubes are following
![(a+b)(a^2 -ab +b^2) = a^3+ b^3 \\\\\\(a - b)(a^2+ ab+ b^2) = a^3 - b^3](https://tex.z-dn.net/?f=%28a%2Bb%29%28a%5E2%20-ab%20%2Bb%5E2%29%20%3D%20a%5E3%2B%20b%5E3%20%5C%5C%5C%5C%5C%5C%28a%20-%20b%29%28a%5E2%2B%20ab%2B%20b%5E2%29%20%3D%20a%5E3%20-%20b%5E3)
(a)
![(x-4) \left(x^{2}+4 x-16\right)\\=(x-4) \left(x^{2}+4 x-4^2\right)\\\\](https://tex.z-dn.net/?f=%28x-4%29%20%5Cleft%28x%5E%7B2%7D%2B4%20x-16%5Cright%29%5C%5C%3D%28x-4%29%20%5Cleft%28x%5E%7B2%7D%2B4%20x-4%5E2%5Cright%29%5C%5C%5C%5C)
by comparison with formula we can say that this is neither sum or nor difference of cubes.
(b)
![(x-1)\left(x^{2}-x+1\right)\\=(x-1)\left(x^{2}-x+1^2\right)](https://tex.z-dn.net/?f=%28x-1%29%5Cleft%28x%5E%7B2%7D-x%2B1%5Cright%29%5C%5C%3D%28x-1%29%5Cleft%28x%5E%7B2%7D-x%2B1%5E2%5Cright%29)
by comparison with formula we can say that this is neither sum nor difference of cubes.
(c)
![(x+1)(x-1)=x^{2}-1^{2}\\](https://tex.z-dn.net/?f=%28x%2B1%29%28x-1%29%3Dx%5E%7B2%7D-1%5E%7B2%7D%5C%5C)
we can say that this is neither sum nor difference of cube as it's difference of squares.
(d)
![(x+4)\left(x^{2}-4 x+16\right)\\\\(x+4)\left(x^{2}-4 x+4^2\right)](https://tex.z-dn.net/?f=%28x%2B4%29%5Cleft%28x%5E%7B2%7D-4%20x%2B16%5Cright%29%5C%5C%5C%5C%28x%2B4%29%5Cleft%28x%5E%7B2%7D-4%20x%2B4%5E2%5Cright%29)
by comparison with formula this is equal to
![x^{3}+4^{3}\\](https://tex.z-dn.net/?f=x%5E%7B3%7D%2B4%5E%7B3%7D%5C%5C)
Hence this is sum of cubes
(e)
![(x+4)\left(x^{2}+4 x+16\right)\\(x+4)\left(x^{2}+4 x+4^2\right)](https://tex.z-dn.net/?f=%28x%2B4%29%5Cleft%28x%5E%7B2%7D%2B4%20x%2B16%5Cright%29%5C%5C%28x%2B4%29%5Cleft%28x%5E%7B2%7D%2B4%20x%2B4%5E2%5Cright%29)
by comparison with formula we can say that this is neither sum nor difference of cubes.
