Answer:
15
Step-by-step explanation:
Just substitute the x for 5
In this case:
Original function: f(x) = - 2x
Substitute function: f(5) = - 2(5)
Now solve for the substitute function
- 2(5)
25 - 10
15
Therefore, f(5) is equal to 15
Answer:
Sequence :
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio .
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is .
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
