question 1

For each graph below, state whether it represents a function. Graph 1 Graph 2 Graph 3 O NO OYes ONO OYes ONO Function? OYes Graph 5 Graph 6 Graph 4 Ty 1-J 2- -3- O No OYes OYes O No OYes Function? ONOThe functions f, g, and h are defined as follows. x+1 f(x) = -15 +12x| g(x) = h (x) =vx-2-5 1+x Find f 4 J. 8(-5), and h (5). Simplify your answers as much as possible. 4 X 5 ? 8 (-5) = 0 h (5 ) = 0The function h is defined below. 2 X + 2x -24 h (x) = 2 x- 81 Find all values of x that are NOT in the domain of h. If there is more than one value, separate them with commas. = 0.0 X 5 ?The entire graph of the function g is shown in the figure below.
