7 I think, I’m sorry if I’m wrong
Answer:
What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve
Step-by-step explanation:
The answer to your problem is: 122.32
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.
![g(-2)=5(-2)+4\\g(-2)=-6](https://tex.z-dn.net/?f=g%28-2%29%3D5%28-2%29%2B4%5C%5Cg%28-2%29%3D-6)
So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)
![f(g(-2))=f(-6)\\f(-6)=8-10(-6)\\f(-6)=8+60\\f(-6)=68](https://tex.z-dn.net/?f=f%28g%28-2%29%29%3Df%28-6%29%5C%5Cf%28-6%29%3D8-10%28-6%29%5C%5Cf%28-6%29%3D8%2B60%5C%5Cf%28-6%29%3D68)
68 is the answer
