Answer:
C
Step-by-step explanation:
Let's just look at the point G(3) = 3
this point only occurs through one equation which is
g(x) = (1/3)x^2
Answer:
![\frac{-3+ 2\sqrt{3}}{2}\textrm{ and }\frac{-3- 2\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%2B%202%5Csqrt%7B3%7D%7D%7B2%7D%5Ctextrm%7B%20and%20%7D%5Cfrac%7B-3-%202%5Csqrt%7B3%7D%7D%7B2%7D)
Step-by-step explanation:
![3(2b+3)^{2}=36\\\frac{3(2b+3)^{2}}{3}=\frac{36}{3}\\(2b+3)^{2}=12](https://tex.z-dn.net/?f=3%282b%2B3%29%5E%7B2%7D%3D36%5C%5C%5Cfrac%7B3%282b%2B3%29%5E%7B2%7D%7D%7B3%7D%3D%5Cfrac%7B36%7D%7B3%7D%5C%5C%282b%2B3%29%5E%7B2%7D%3D12)
Taking square root both sides, we get
![\sqrt{(2b+3)^{2}}=\pm \sqrt{12}\\2b+3=\pm \sqrt{4\times 3}\\2b+3=\pm 2\sqrt{3}\\2b+3-3=\pm 2\sqrt{3}-3\\2b=-3\pm 2\sqrt{3}\\b=\frac{-3\pm 2\sqrt{3}}{2}\\b=\frac{-3+ 2\sqrt{3}}{2}\textrm{ or }b=\frac{-3- 2\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282b%2B3%29%5E%7B2%7D%7D%3D%5Cpm%20%5Csqrt%7B12%7D%5C%5C2b%2B3%3D%5Cpm%20%5Csqrt%7B4%5Ctimes%203%7D%5C%5C2b%2B3%3D%5Cpm%202%5Csqrt%7B3%7D%5C%5C2b%2B3-3%3D%5Cpm%202%5Csqrt%7B3%7D-3%5C%5C2b%3D-3%5Cpm%202%5Csqrt%7B3%7D%5C%5Cb%3D%5Cfrac%7B-3%5Cpm%202%5Csqrt%7B3%7D%7D%7B2%7D%5C%5Cb%3D%5Cfrac%7B-3%2B%202%5Csqrt%7B3%7D%7D%7B2%7D%5Ctextrm%7B%20or%20%7Db%3D%5Cfrac%7B-3-%202%5Csqrt%7B3%7D%7D%7B2%7D)
Therefore, the values of
are:
![\frac{-3+ 2\sqrt{3}}{2}\textrm{ and }\frac{-3- 2\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%2B%202%5Csqrt%7B3%7D%7D%7B2%7D%5Ctextrm%7B%20and%20%7D%5Cfrac%7B-3-%202%5Csqrt%7B3%7D%7D%7B2%7D)
