Answer: D

Explanation:

g(x)=f(x-2)=8(x-2)+1=8x-16+1=8x-15

We are given that ;

  • f(x) = 8x + 1
  • g(x) = f(x-2)

And we need to find g(x) in simplified form . For this we will consider f(x) and then substitute x by x-2 .


{:\implies \quad \sf f(x)=8x+1}

Now ,


{:\implies \quad \sf f(x-2)=8(x-2)+1}


{:\implies \quad \sf g(x)=8x-16+1\quad \qquad \{\because Given\}}


{:\implies \quad \bf \therefore \quad \underline{\underline{g(x)=8x-15}}}

Hence , Option D) 8x - 15 is correct
