Answer:
g(f(x)) =3(x2)+1
Step-by-step explanation:
g(f(x)) means substitute f(x) in the eqn g(x)
That is anywhere you see x2, use it to replace x in the eqn g(x)
An arithmetic sequence is a sequence of numbers with a common difference.
In the choices above, only A and D are arithmetic sequences.
<em>In A, the common difference is 2 while in D, it's 0 .1.
</em>
B can't be an arithmetic sequence since the number 1 is just being repeated many times, there's no progression.
C as well. Be observant of the pattern, it can be an arithmetic sequence only if it has 4 before 5.
E obviously is not an arithmetic sequence. If you try to find the difference between the consecutive terms, it's not common.
Answer:
a. f(x) = 21 (20) +1 (25) = 445
b. The scenario is a function because each student just have to pay once.
Answer:
75%
