Answer:
a=
15
b=1/3
Step-by-step explanation:
- key rule: see the graph carefully to get the following identified points.
- from the given graph, it can be seen that, the curve passes through (0,15)
- by substituting this point in y=a*(b)^x,
15=a*(b)^0
15=a
- it can also be seen that the curve passes through (1,5)
- by substituting this point in y=a*(b)^x,
5=a*b
5=15*b ( since, we have found that a=15 from the before steps)
- dividing both the sides by 15,
5/15=b=1/3
a=
15
b=1/3.
