The value of f(25) and f(-66) are 3 and -4 respectively
<h3>Functions and values</h3>
Given the function below:
To get the value of f(25), we will substitute x = 25 into the function to have:
Similarly for f(-66)
Hence the value of f(25) and f(-66) are 3 and -4 respectively

Answer:
36 boys are going on the trip
Step-by-step explanation:
given data
total students = 48
girls = One-fourth
to find out
How many boys are going on the trip
solution
first we find One-fourth part of total students
so total girls are One-fourth that mean =
girls = = 12
if there 12 girls so remaining are boys
so boys are = total students - girls
boys = 48 - 12
boys = 36
so 36 boys are going on the trip
Answer:
not arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
Given
= 2n² - 1
Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence
= 2(1)² - 1 = 2 - 1 = 1
= 2(2)² - 1 = 8 - 1 = 7
= 2(3)² - 1 = 18 - 1 = 17
= 2(4)² - 1 = 32 - 1 = 31
check the difference between consecutive terms
7 - 1 = 6
17 - 7 = 10
31 - 17 = 14
The differences are not common hence not an arithmetic sequence
