I'm pretty sure it would be true because an advocate for women's rights, for example, speaks out about women's rights because they believe women should have rights.

Which function is an extended function

likoan [24]

Answer:

D. The last option

Explanation:

You can't divide by 0, so find out when the given function is discontinuous.

$\frac{x^3+3x^2-x-3}{x^2-1} =\frac{x^3+3x^2-x-3}{(x+1)(x-1)}$

You can see that x is discontinuous at x=-1,1, so find a piecewise function that fill in those gaps.

Plug x=-1,1 into your function to find out what values you need to fill in. But of course it's discontinuous at those points, so plug in a number near x=1 and x=-1. I chose x=-1.1 and x=1.1

$f(-1.1)\frac{(-1.1)^3+3(-1.1)^2-(-1.1)-3}{(-1.1)^-1} = 1.9 \approx 2$

$f(1.1)\frac{(1.1)^3+3(1.1)^2-(1.1)-3}{(1.1)^-1} = 4.1 \approx 4$

so we need to fill in 2 at x=-1, and fill in 4 at x=1
