Question

Write an exponential function in the form y=ab^xy=ab
x
that goes through points (0, 8)(0,8) and (3, 8000)(3,8000)

Answer 1

Answer:

y = 8 · 10ˣ

Step-by-step explanation:

y = abˣ

When x = 0, y = 8.

8 = ab⁰

8 = a

When x = 3, y = 8000.

8000 = 8b³

1000 = b³

10 = b

The function is:

y = 8 · 10ˣ
