Question

Please just tell me if I'm right or wrong!

Answer 1

The first one is incorrect

Answer 2

but the second one is correct

Answer 3

Hmm... Let me try it again then...

9-0^2 = 9-0 = 9 < 0 (It's wrong, so it doesn't work out)
9 x=0 0=0 (correct)
-4(0)+9 = 9 = 9>0 ( correct)

Answer 4

That x < 0 is just telling you which part to graph

Answer 5

it has nothing to do with the final evaluation

Answer 6

all you're doing is finding out if the limit exists (and if it does, which value is it)

Answer 7

9?

Answer 8

@jim_thompson5910

is it 9?

Answer 9

yes, as x approaches 0, f(x) approaches 9
