Respuesta :

Given: A rational function

[tex]r(x)=\frac{4}{x^2+3x-5}[/tex]

Required: x-intercept and y-intercept of the function

Explanation:

for x-intercept, y = 0

In this case r(x) = 0

which is not possible.

So x-intercept doesnot exist.

For y-intercept, x = 0

Put x = 0

[tex]r(x)=\frac{4}{0+0-5}=-\frac{4}{5}[/tex]

So y is -4/5.

Final Answer:

x-intercept: DNE

y-intercept: (0,-4/5).
