No because x^2+4 cannot be factored over the integers. I’m certain it was x^2+4

you cant factor (X^2+4)

the one where g(x) = f(x), why couldn’t that be the actual coordinates with (-.99, whatever)

It feels like I’m forgetting a bunch of the short answer ones

I just know it wasn’t because then 3 and 4 would be right. Also, the solution is the x-value I think.

Yea I also put the coordinate one

That’s the mistake they wanted you to make. (x^2+4) is factored into x±2i, which isn’t over the set of integers

The thing is that both the coordinates were correct so either it was the correct one without the coordinate or the question would be invalidated for having more than one answer.

@kimclan1 did u get any of the questions wrong?

i checked every possible solution with the calculator and got that to be the only possible answer but idk i might be wrong

for the logs graph one, what did you guys put for the explanation? and for the graph did we just have to plug in our calculator and pull up the table?

idk if we talked about it already but the system of equations question…
x=0 y=2 z=-1

there wasn’t an explanation for the log graph, we just had to state end behavior

I have no idea. The two I am iffy on is #22 with the compounded interest because what I am hearing I misread it and with the one where you were given the population from 2010 people are saying it was 2, only but I said neither since the rate was closer to 4.0% than 3.9%.

for the log graph with log(x+3)/log(2) - 5, you had to plot (0,-2.6whatever) AND (29,0) cuz it asked for both intercepts with an appropriate scale and also asymptote being x = -3

I got a 100 on geometry last year though if that’s worth anything

How?

Ok good that’s what I did

i’m pretty sure the equation stated 100e^0.03922t which would be 3.9 right? unless my memory is failing me

Yeah they said to have an interval with both intercepts so the scale will probably just require you to have both the intercepts in the right places and a reasonable sketch (not going less than -3 on x)
