Question

If f(x) = 7 + 4x and g (x) = StartFraction 1 Over 2 x EndFraction, what is the value of (StartFraction f Over g EndFraction) (5)?

Answer 1

270

Explanation:

f(5) = 7 +4·5 = 27

g(5) = 1/(2·5) = 1/10

The ratio of functions is the ratio of their individual values:

(f/g)(5) = f(5)/g(5) = 27/(1/10)

(f/g)(5) = 270
