Welcome To Class : XI Subject : Maths Chapter : 1 Exercise : 1.4 Que 1 : For the curve y = x³ given in Figure, draw (i) y = -x³ (ii) y = x³ + 1 (iii) y = x³–1 (iv) y = (x + 1)³, with the same scale. Solution : (i) y = -x³ y=-f(x) It is the reflection of the graph of f  About the x-axis (ii) y = x³ + 1 The graph of y = f(x) + 1 is shifted upward to 1 unit. (iii) y = x³ – 1 The graph of y  = x³ – 1 is shifted downward  to 1 unit (iv) y = (x + 1)³ The graph of y  = (x + 1)³ is shifted to  the left for 1 unit. Que 2 :                                     For the curve, y = (x^⅓) given in figure draw. (i) y = (-x^⅓) (ii) y=(x^⅓) +1 (iii) y= (x^⅓) -1 (iv) y=(x+1)^⅓ Solution : (i) y = (- x)^⅓ Then y = -x^⅓ is the reflection of the graph of y=x^⅓ about the x-axis. (ii) y=(x^⅓) +1   Then y= (x^⅓)+1 is the x graph of y = x^⅓ shifts to the upwards for one unit. (iii) y= (x^...
