Answer: The complete question is found in the attachment
Step-by-step explanation:
a) To determine the 1-unit growth factor for f
= 2.1/1.75 = 1.2
b) To determine the 1-unit percent change for f
=100 x 1-1.2/1 = 0.2 x 100= 20%
c) to determine the initial value of f
f(x)= abˣ , b =1.2 a=initial value
at (-1,2.1)
2.1= (1.2)⁻¹ x a
a = 2.1/(1.2)⁻¹
a = 2.1 x 1.2 = 2.52
d) to determine the function formula for f
f(x)= abˣ = 2.52(1.2)ˣ
