Question

If (x)=3x-1 and s(x)=2x+1, which expression is equivalent to r over s (6) ?

Answer 1

`\large\boxed{(3(6)-1)/(2(6)+1)}`

Explanation:

`\left((f)/(g)\right)(x)=(f(x))/(g(x))\\\\\text{We have}\\\\f(x)=3x-1,\ g(x)=2x+1\\\\\left((f)/(g)\right)(x)=(3x-1)/(2x+1)\\\\\left((f)/(g)\right)(6)\to\text{put x = 6 to the equation of the function}\ \left((f)/(g)\right)(x):\\\\\left((f)/(g)\right)(6)=(3(6)-1)/(2(6)+1)`
