Find a formula for the exponential function of the form
A=f(t)=IB^t passing through the points (2.1, 21) and (4.9, 11)
A=f(t)
A=f(t)=IB^t passing through the points (2.1, 21) and (4.9, 11)

f(t) = a*b^t
a*b^2.1 = 21
a*b^4.9 = 11
divide to get
b^2.8 = 11/21
now finish it off
a*b^2.1 = 21
a*b^4.9 = 11
divide to get
b^2.8 = 11/21
now finish it off
