question 1

For each relation, decide whether or not it is a function. Relation 1 Relation 2 Domain Range Domain Range d m -6 sky W d -8 star 7 desk d 4 leaf -9 moon O Function Not a function O Function O Not a function Relation 3 Relation 4 ((9, 6). (9, 8). (9, 2). (9, 9)} {(b, 3). (a, 4), (g. 6). (u. -9)} O Function O Function O Not a function O Not a functionFor each graph below, state whether it represents a function. Graph 1 Graph 2 Graph 3 -2- OYes ONO OYes ONO OYes ONO Function? Graph 4 Graph 5 Graph 6 TF 2- 4 12- -3- OYes ONO Function? OYes ONO OYes ONOThe functions f, g, and h are defined as follows. 2 1+x f (x) = 9x - 14 g (x) =\\x-3 -2 h(x) = x+1 Find f 3 J. 8 (6), and h (-5). Simplify your answers as much as possible. OVO X 5 ? 8 (6) = 1 h (-5) = 1The function g is defined below. 2 g ( x ) = X +7x - 18 2 x- 81 Find all values of x that are NOT in the domain of g. If there is more than one value, separate them with commas. X 0.0.. X 5
