If f(x) = 7 + 4x and g(x) = 1/2x, what is
the value of (f/g) (5)?
1) 11/2
2) 27/10
3) 169
4) 270

Answer 1

270

Explanation:

We have to find (f/g)(5).

Now, (f/g)(x) = (7 + 4x)/(1/2x)

= (7 + 4x)(2x)

= 14x + 8x2

Put x = 5 in the above expression,

(f/g)(5) = 14(5) + 8(5)2

= 70 + 8(25)

= 70 + 200

= 270
