Given that f -1 f (2) = (11) = 2 Given that f -1 f (-1) = (2) = -1 Given that f (8) =-7 f -1 ( ) = 8 the inverse is since Given that f -1 f (11) = f -1 (x) = 2x + 5 (3) = hence the inverse is since Given that f -1 f -1 f (9) = (x) = 2x + 5 ( ) =9 and Given that since f (-4) =-3 f -1 f -1 f (x) = ax + 5 (-3) = (-4) = -3 find a ? therefore and Given that since f (-4) =-3 a( ) + 5 = -4 f -1 f -1 (x) = ax + 5 f (-3) = -4 (-4) = -3 a= find a ? therefore and Given that since f (6) =2 b( 2 ) -2 = 6 f -1 f -1 (x) = bx - 2 f (2) = 6 (6) = 2 b= find b ? and Given that f (-5) =-1 f -1 g= (x) = gx - 3 find g ? and Given that f -1(15) =2 f k= (x) = 5-kx find k ? find Let y= Given that therefore f -1(7) x= f 5-2x (x) = 5-2x A. B. C. Choose the correct answer A. B. 5-y y-5 2 2 C. 5-2 y find Let y= f -1 Given that so (x)= f -1(7) f 5-2x 5-x (x) = 5-2x 2 therefore = f -1 (7) find Let y= Given that therefore f -1(-6) x= f 7x+1 (x) = 7x +1 A. B. C Choose the correct answer A. B. 1-y y-7 7 1 C. y-1 7 Given that find f -1(-6) f -1(x) f -1(-6) f (x) = 7x +1 = = - Given that find f -1(5) f -1(x) f -1(5) f (x) = 4x -3 = = Given that find f -1(5) f -1(5) f (x) = 2x -7 = Given that find f -1(-4) g g -1(-4) (x) = 3 -7x = Given that find g(7) g = (7) ? g -1(-4) = 7 Given that find h -1(-4) h -1(-4) = h (x) = 3-2x 2 h Given that (x) = h -1(-2) x+1 3 find = ;x h -1(-2) ≠ -1 |
