Answer:
The answer to your question is f⁻¹(x) = ![\frac{1}{2} x - \frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%5Cfrac%7B3%7D%7B2%7D)
Step-by-step explanation:
Function
f(x) = 2x + 3
Process
1.- Instead of f(x) write y
y = 2x + 3
2.- Interchange the variables
x = 2y + 3
3.- Solve for y
- Subtract 3 in both sides
x - 3 = 2y + 3 - 3
x - 3 = 2y
- Divide by 2
![\frac{1}{2} x - \frac{3}{2} = y](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%5Cfrac%7B3%7D%7B2%7D%20%3D%20y)
4.- Write f⁻¹(x) instead of y
f⁻¹(x) = ![\frac{1}{2} x - \frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%5Cfrac%7B3%7D%7B2%7D)
Answer:
V = 672cm^3
Step-by-step explanation:
V of irregular figure = lwh + lwh
V = 7(3)(2) + 10(7)(9)
V = 42 + 630
V = 672cm^3
