Question

if f(x)= square root of x+12 and g(x)=2 square root of x, what if the value of (f-g)(144)

Answer 1

\(\large f(x) = \sqrt{x+12}\)

\(\large g(x) = 2\sqrt{x}\)

Answer 2

like that ?

Answer 3

Yes!

Answer 4

or may be like this :

\(\large f(x) = \sqrt{x} + 12\)

\(\large g(x) = 2\sqrt{x}\)

Answer 5

First one.

Answer 6

wait, no. The second.

Answer 7

haha yes the second one makes more sense

Answer 8

use below :
\(\large (f-g)(144) = f(144) - g(144)\)

Answer 9

evaluate f(x) at x = 144
evaluate g(x) at x = 144

and subtract

Answer 10

So, 0.

Answer 11

Excellent !
