Question

Given y=-x²+10x+24 for -1≤ x ≤ 3, (1) please show step by step of subdividing the interval [-1,3] into four equal parts.

(a) -1, 0, 1, 2, 3
(b) -1, 1, 2, 3
(c) -1, 0.5, 1.5, 2.5, 3
(d) -1, 0.75, 1.5, 2.25, 3

Answer 1

To subdivide the interval [-1,3] into four equal parts, you need to determine the values at each subdivision point. The four equal parts are: x = -1, 0, 1, 2, 3 (a); x = -1, 1, 2, 3 (b); x = -1, 0.5, 1.5, 2.5, 3 (c); x = -1, 0.75, 1.5, 2.25, 3 (d).

Step-by-step explanation:

To subdivide the interval [-1,3] into four equal parts, you need to determine the values at each subdivision point. The four equal parts are:

1. 
   
3. x = -1, 0, 1, 2, 3 (a)
4. 
   
6. x = -1, 1, 2, 3 (b)
7. 
   
9. x = -1, 0.5, 1.5, 2.5, 3 (c)
10. 
    
12. x = -1, 0.75, 1.5, 2.25, 3 (d)
