Answer 1

Is it correct? :-)

Answer 2

haha trick question !
plugin 4 in the function, doesn't the numerator vanish ?

Answer 3

\[\large f(x) = \dfrac{x-4}{x+3}\]

Answer 4

It vanished.... like magic!

Answer 5

to get the value of \(f(4)\) , simply plugin \(x=4\) above ^^

Answer 6

If the numerator is zero what does that make the fraction=?

Answer 7

I got f(x) = 0 @ganeshie8

Answer 8

that is what I got too

Answer 9

yes and the other way to solve it,is graphing f(x) = x-4 / x+3

Answer 10

I plugged it in like this:
f(x) = (4-4)/(4+3)

Answer 11
