Let a function of two variables be defined by $ f(a, b) = ab - (a - b) $. What is the value of $ f(8, 9) $?

1) 89
2) 73
3) 71
4) 34
5) 0

The question is asking for the value of the function f(a,b)= ab-(a-b) when a=8 and b=9. To solve, we replace a and b in the equation with 8 and 9, respectively. So, we will obtain f(8,9)= (8*9)-(8-9). This simplifies to f(8,9)= 72-(8-9), then to f(8,9)= 72-(-1), and finally, f(8,9) = 72+1. Hence, the value of f(8,9) is 73.
