Please help find the indicated intercept(s) of the graph of the function.
x-intercepts of f(x) = 2x+7
____
x-5
**
y = 2x+7/x-5
To find the x-intercept(s), set y, the function=0, then solve for x
Essentially, you are setting the numerator=0.
2x+7/x-5=0
2x+7=0
2x=-7
x=-7/2

The 
-intercepts of a function (or intercept in this case since there is only 1) are all points of the form )
that are on the graph of the function. You have to find a number 
so that \ =\ 0)
\ =\ \frac{2x\ +\ 7}{x\ -\ 5})
Since we are looking for such that
Just set the function equal to zero:
And solve for

My calculator said it, I believe it, that settles it
