Question

how do you find the x and y intercept of f(x)= (1)/(x+2)

Answer 1

x intercept: f(x) = 0, find x that makes f(x) = 0.
y intercept: f(0) = ?, find value of f(0)

Answer 2

can someone explain further

Answer 3

There's not much to explain.
\[f(x) = \frac{1}{x+2}=0\]
Is there a value of x for which that is true? No, not even x = a zillion kajillion :-)
No x intercept.

y intercept is another story.
\[f(0) = \frac{1}{0+2} = \frac{1}{2}\]

So the y intercept is 1/2.

Answer 4

okay thankyou

Answer 5

You can see that the y-intercept is 1/2, and that it doesn't look like it will ever cross the x-axis...
