7. For the graphs below identify the a) the x-intercepts; b) the y-intercepts; c)Domain d) Range and then e) state why the graph is or is not a function. h(x) y = h(x)- 4 1 2 3 4 5 8. Given the function defined by d(x) = _x - 3 and f(x)=x2 find the function values a) (d + f)(-6) b) (d . f)(-6) c) (d . f) (-6) 9. Identify each function as linear, constant, quadratic or none of these a) f(x) = f(x) =4 -3x - 2x2 b) f(x) =5 -12 c) f (x) = 5x-3 6 d) f ( x) = = 9 4-5x
