Given that a function, h, has a domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25 and that h(8) = 19 and h(-2) = 2, select the
1 answer:
The true statement for h regarding the function is that C. h(2) = 16.
<h3>How to illustrate the function?</h3>From the information given, the function, h, has a domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25.
This illustrates that the range or h has to be less than or equal to 25.
The option that correctly fits this is C.

Answer:
The first term is 14
The common difference is -2.5
Step-by-step explanation:
we know that
The rule to calculate the an term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
we have that
The third term of an arithmetic sequence is equal to 9
so
substitute
----> equation A
The rule to find the sum of the the first n terms of the arithmetic sequence is equal to
we have
The sum of the first 8 term is 42
so
substitute
----> equation B
Solve the system of equations
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
the solution is (14,-2.5)
see the attached figure
therefore
The first term is 14
The common difference is -2.5
