Answer:
Step-by-step explanation:
Price of one pound = 1.95
Price of 13.2 pounds = 13.2 x 1.95 = 25.74
![x \leq -2\\ (- \alpha ,-2]](https://tex.z-dn.net/?f=x%20%20%5Cleq%20-2%5C%5C%0A%28-%20%5Calpha%20%2C-2%5D%20)
Note: the infinity character would not render correctly, so I used alpha instead. Pretend it's an infinity sign.
F(x)/g(x) = (2x +3)(x -1)/(x -1) = 2x +3 . . . . . x ≠ 1
The domain of (f/g)(x) is all real numbers except 1.
