Answer:
![f(x)=x^3-7x-6](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3-7x-6)
Step-by-step explanation:
If x = 3 is a root of a polynomial f(x), then x - 3 is a factor of this polynomial.
If x = -2 is a zero of a polynomial function f(x), then f(-2) = 0 and x - (-2) = x + 2 is a factor of f(x).
If x = -1 is an x-intercept of the function, then y = 0 and x - (-1) = x + 1 is also a factor of the function f(x).
Therefore, the polynomial expression is
![f(x)=(x-3)(x+2)(x+1)](https://tex.z-dn.net/?f=f%28x%29%3D%28x-3%29%28x%2B2%29%28x%2B1%29)
In standard form:
![f(x)=(x-3)(x^2+2x+x+2)=(x-3)(x^2+3x+2)=x^3+3x^2+2x-3x^2-9x-6=x^3-7x-6](https://tex.z-dn.net/?f=f%28x%29%3D%28x-3%29%28x%5E2%2B2x%2Bx%2B2%29%3D%28x-3%29%28x%5E2%2B3x%2B2%29%3Dx%5E3%2B3x%5E2%2B2x-3x%5E2-9x-6%3Dx%5E3-7x-6)
Answer:
You have a chance of getting any of those.
Step-by-step explanation:
If you were to flip the first coin, and it would be either heads or tails 50% chance.
If you flipped the second coin, without cancelling the first, it would be 25% chance
If you flipped the third coin, without cancelling the first it would be 12.5% chance
(this is all for heads)
Answer: the answer is x=7.5
