Question

प्रश्न 1: मान लीजि ए f : R → R और g : R → R, f (x) = 8x - 6 और g(x) = 4x 2 + 6, द्वारा परि भाषि त है, तो fog(x) और gof(x) ज्ञात कीजि ए। love is play with two side explain​

Answer 1

=> Here, f : R→R and g : R→R are two functions.

f (x) = 8x - 6 ; g(x) = 4x²+ 6

fog(x)

=f(g(x))

=f(4x²+6)

=(8(4x²+6)-6)

=(32x²+48-6)

= 32x²+42

gof(x)

=g(f(x))

=g(8x - 6)

=(4(8x-6)²+6)

=(4(64x²-96x+36) +6

=(256x²-384x+144+6)

= 256x²-384x+150
