Answer:
B
Step-by-step explanation:
To find the y- intercept let x = 0
From the table for f(x)
When x = 0 → f(x) = - 4
That is the y- intercept = - 4
Given
g(x) = 3
let x = 0 , then
g(0) = 3 [
= 1 ]
= 3 × 1
= 3
That is the y- intercept = 3
Thus the y- intercept of g(x) is greater → B
Answer:
(a) 4.152698
(b) 3.215557
Step-by-step explanation:
(a)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
Now, the midpoints of these subintervals are:
Hence:
(b)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
[1,5], [5,9], [9,13]
The endpoints of the subintervals consist of:
5,9
Hence:
