Answer:
= 3n + 77
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then
= 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77
Answer:
The growth value of the function is One-third ⇒ True (2nd)
The function shows exponential decay ⇒ True (3rd)
The function is a stretch of the function ⇒
True (4th)
Step-by-step explanation:
* <em>Lets revise the form of the exponential function</em>
- The general form of the exponential function is
where "a" is the initial amount and "b" is the growth factor
- If b > 1, then f(x) is exponential growth function
- If 0 < b < 1, then f(x) is exponential decay function
* <em>Lets solve the problem</em>
- The exponential function
∴ The initial value is 3
∴ The growth factor is
∵ The growth factor is less than 1
∴ f(x) is exponential decay function
* Lets chose the true statements
# The initial value of the function is One-third ⇒ Not true
because the initial value is 3
# The growth value of the function is One-third ⇒ True
because the growth factor is
# The function shows exponential decay ⇒ True
because the growth factor is less than 1
# The function is a stretch of the function
⇒ True
because stretched vertically means multiply f(x) by constant greater
than 1 and 3 is greater than 1
# The function is a shrink of the function ⇒ Not true
because the growth factor is not 3
