Question

Determine the 1-unit growth factor for f f. [We encourage you to write the expression that represents the value of the growth factor rather than a rounded decimal. If you choose to use rounded answers, round to five decimal places.]

Answer 1

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
