3) Circle the function that's increasing over its entire domain. (X - / mark) =5r + 3x+2 y=-31-7 -2'+6 y=V-x 4) Circle the function that has a discontinuity at x =4. (K - I mark) (x +5, x55 2 / x-7. x54 y = +3 x' -2, 1>5 y = 2x -8 -3x +9, x>4 5) Circle the function that has odd symmetry. (K - 1 mark) 2 y= yer +8 y= 3x+7 y =2' 3x 6) For the function f(x) =5x- -30x + 2. state the intervals of increase and decrease. (K - 3 marks)
