Step-by-step explanation:
Answer:
Option 4 is the correct option.
Step-by-step explanation:
We need to solve the expression 2x(x+2)(x-3)
Multiplying the terms with each other we get,
![2x(x+2)(x-3)\\=2x(x^2 -3x+2x-6)\\=2x(x^2 -x -6)\\=2x^3 -2x^2 -12x](https://tex.z-dn.net/?f=2x%28x%2B2%29%28x-3%29%5C%5C%3D2x%28x%5E2%20-3x%2B2x-6%29%5C%5C%3D2x%28x%5E2%20-x%20-6%29%5C%5C%3D2x%5E3%20-2x%5E2%20-12x)
Option 4 is the correct option.
68% x 12 = 8.16
Multiply 68% by 12 to get answer
Answer: ![f(-64)=0](https://tex.z-dn.net/?f=f%28-64%29%3D0)
![f64)=0](https://tex.z-dn.net/?f=f64%29%3D0)
Step-by-step explanation:
The given function : ![f(x)=16-x^{2/3}](https://tex.z-dn.net/?f=f%28x%29%3D16-x%5E%7B2%2F3%7D)
When we substitute x= -64, we get
![f(x)=16-(-64)^{2/3}](https://tex.z-dn.net/?f=f%28x%29%3D16-%28-64%29%5E%7B2%2F3%7D)
Since , ![64=4\times4\times4=4^3](https://tex.z-dn.net/?f=64%3D4%5Ctimes4%5Ctimes4%3D4%5E3)
So, ![-64=-4\times-4\times-4=-4^3](https://tex.z-dn.net/?f=-64%3D-4%5Ctimes-4%5Ctimes-4%3D-4%5E3)
That means ![f(-64)=16-(-64)^{2/3}=16-(-4^3)^{2/3}](https://tex.z-dn.net/?f=f%28-64%29%3D16-%28-64%29%5E%7B2%2F3%7D%3D16-%28-4%5E3%29%5E%7B2%2F3%7D)
![=16-(-4)^2=16-(-4\times-4)=16-16=0](https://tex.z-dn.net/?f=%3D16-%28-4%29%5E2%3D16-%28-4%5Ctimes-4%29%3D16-16%3D0)
i.e. ![f(-64)=0](https://tex.z-dn.net/?f=f%28-64%29%3D0)
Similarly, When we substitute x= 64, we get
![f(x)=16-(64)^{2/3}](https://tex.z-dn.net/?f=f%28x%29%3D16-%2864%29%5E%7B2%2F3%7D)
Since , ![64=4\times4\times4=4^3](https://tex.z-dn.net/?f=64%3D4%5Ctimes4%5Ctimes4%3D4%5E3)
That means ![f(64)=16-(64)^{2/3}=16-(4^3)^{2/3}](https://tex.z-dn.net/?f=f%2864%29%3D16-%2864%29%5E%7B2%2F3%7D%3D16-%284%5E3%29%5E%7B2%2F3%7D)
![=16-(4)^2=16-16=0](https://tex.z-dn.net/?f=%3D16-%284%29%5E2%3D16-16%3D0)
i.e. ![f64)=0](https://tex.z-dn.net/?f=f64%29%3D0)
