The answer you have selected is correct. The answer to this question is 90.
If f(x) = (5x + 1) /2
Ok, you need to find inverse function, here's how...
1. Change "f(x)" to y, to make the calculations easier. y = (5x + 1) /2 2. Switch x and y: x = (5y + 1) /2 3. Solve for y: x = (5y + 1) /22x = 5y + 12x - 1 = 5y(2x - 1) / 5 = y 4. Change "y" to f-1(x) (2x - 1) / 5 = f-1(x) Now, plug in 8 for x to get the answer: (2*8 - 1) / 5 = (16 - 1) / 5 = 15/5 = 3
Hope this helps :)
