The answer is 35.
Decay factor is 0.77 ; y-intercept is 9 ⇒ answer a
Step-by-step explanation:
The form of the exponential function is , where
- a is the y-intercept (at x = 0)
- b is the growth/decay factor
- If b > 1, then it is a growth factor
- If 0 < b < 1, then it is a decay factor
∵
- To find the y-intercept put x = 0
∴
∵
∴ y = 9(1) = 9
∴ The y-intercept is 9
∵
∵
∵ b = 0.77
∵ 0 < 0.77 < 1
∴ 0 < b < 1
∴ The decay factor = 0.77
Decay factor is 0.77 ; y-intercept is 9
