Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
<u><em>Step(ii):-</em></u>
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒
⇒ 64 = b³
⇒ 4³ = b³
b = 4
<u><em>Final answer:-</em></u>
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)
