The answer is (2,1). 2*2=4 and 9*1=9. 9+4=13
You would round down to 25,000
constant term in any function is the term whose value does not change on variation of other parameters or in other case. We can also say constant term is independent of variable parameters.
take example
y = x + 3
here 3 is constant term which will not change either I change x or y . 3 is independent . it's just helps equation to hold information that overall in equation its matter.
so in given problem -4 is the constant
