A

Edit: Actually I think it's D since it's a continuous function.

i tried that man, came up dry

a and d both agree that the range is y is greater than 4 but disagree on whether the domain is a set of integers or all real numbers

can anyone explain why its a set of integers rather than all real numbers?

but X is still all just integers

We don't see the whole function, just certain pairs in the function.

But the description of the function is that it's a continuous exponential function. That means it must still exist between integers, and being exponential y is going to be > 0. Actually, that makes me think C might be right lol, because we could have negative X values.

Function is continuous so domain is the reals

function is exponential so range is greater than f(0) which is 4...maybe

Its continuous

f(0) exists and f(1) exists so everything in between exists

I think C as well, same reasoning for it being all real numbers (its a continuous function not a discrete function).

Plus when X = 0, we have Y = 4... so that eliminates the answers w/ the range of Y is always greater than 4 (it is not a greater than or equal to sign).

ah good point. Missed that

change my answer to c

The answer is C.

its continuous so the domain is all real numbers (eliminating A and B)

the range must be y > 0, because 4 cannot be the minimum of the function (an increasing exponential function has no minimum), so the horizontal asymptote must be lower than y = 4 (eliminating D). Therefore the only answer that works is C.

Huh. Well I did go with C. That was the only answer I was unsure of and I did pass the quiz.

I don't have access to look at the questions I missed or see why I got an answer right but the explanations on here were really helpful. I appreciate that guys. Thanks!

Its definitely C

did you get why the domain has to be the reals?

I get it, its because its continuous function rather than having distinct and separate values
