The exponential function is given by y = 0.9(1.082)ˣ
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the fish weights at x inches.
Using point (4, 1.24):
1.24 = ab⁴ (1)
Using point (10, 1.99):
1.99 = ab¹⁰ (2)
From equation 1 and 2:
b = 1.082, a = 0.9
The exponential function is given by y = 0.9(1.082)ˣ
