If $a$ and $b$ are positive integers such that $\gcd(a, b)=210$, $\mathop{\text{lcm}}[a, b]=210^3$, and $a

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

the first one

just id the test.
