The graph of an exponential function passes through (2,−12) and (3,−24). Find the exponential function that describes the graph.

no fancy math here, just some reasoning with words. I just feel like it

for one step in x-direction the value of the function doubles, so the common factor is 2.

so let's trace it back

(1,-6)

(0, -3)

For an exponential function the y-intercept is the "initial value".

do let's write is as a function

you could also use the points and plug their numbers into the general formula, but I felt this explanation could give you more understanding, since it's meant to be more intuitive.

hope it helps

1.The number 12 is a composite number.

2. The numbers which are divided only by 1 and the number itself is a prime number. The rest of the numbers are composite. the number 12 has factors like 1,2,3,6 &12 so it is a composite number.
