प्रश्न

The function f and g are defined by f(x) = 6x + 8; g(x) = `(x - 2)/3`

 Calculate the value of `"gg" (1/2)`

बेरीज

उत्तर

`"gg" (1/2) = "g"["g"(1/2)]`

= `"g"[1/2 - 2 ÷ 3]`

= `"g"[(1 - 4)/2 ÷ 3]`

= `"g"[(-3)/2 xx 1/3]`

= `"g"[- 1/2]`

= `[- 1/2 - 2 ÷ 3]`

= `[(-1 - 4)/2 ÷ 3]`

= `[(-5)/2 xx 1/3]`

`"gg" (1/2) = - 5/6`
