Answer:
D. The last option
Explanation:
You can't divide by 0, so find out when the given function is discontinuous.
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
so we need to fill in 2 at x=-1, and fill in 4 at x=1
Since you didn't write the signs, I have to make some suggestions, this is what I assume:
<span>If ƒ(x )= 2x²+3, then ƒ(x - 1)= 2x²+4x+5.
So, how much is </span><span>ƒ(x-1?)
it would be= 2(x-1)²+3=</span>2(x-1)<span>(x-1)+3=</span>2(x²-2<span>x+1)+3=</span>2x²-4x+2+3=2x²-4<span>x+5
So, yes, if my assumption is correct, then it's true!
