Can someone help me please

function is

Step-by-step explanation:

The general form for an exponential function is .   We need to find both k and b

(0, 3) is a point on the graph.  So, let's substitute 0 in for x and 3 in for y

Now we know that k = 3

(1, 18) is a point on the graph.  So, let's substitute 1 in for x, 18 in for y and 3 in for k

Now we know that b = 6

Therefore, the function is

That's not too bad, isn't it?

after simplifying it i got: -36.25 as my answer. hope that !

i believe that the answer is

b. y-1=-2(x-4)

hope this !
