Question

Given: f(x) = x2 + 3x – 5 and 2g(x) = 2x – 8. Find (f + g) (x).

Answer 1

The fare rate for x miles is:

`x^2-5x`

and there is a base fare, which means that even for zero miles, the user have to pay "4". Hence the total cost for a ride of x miles is the fare rate plus the base fare:

`x^2-5x+4`

Hence the answer is the last option, x^2-5x+4
