Consider the table giving the values for variables s and t . s 6 1 5 10 4 t -4 1 -6 -7 1 Is s a function of t ? Is t a function of s . Show your work. Solutions. We begin by checking to see if we have s = f ( t ) being a valid function. But, because we have that f (1) = 1 and f (1) = 4 , we see that we cannot have such a function f ( t ).
