Suppose we take the interval [−5,7] and divide it into 4 equal subintervals. find the width δn of each subinterval. δn = if we name the endpoints of the subintervals x0, x1, x2, x3 and x4 , with x0 on the left and x4 on the right, find the values of these endpoints and list them in ascending order. (enter your answers in a comma-separated list.)

Δn=3

Step-by-step explanation:

Remember, if we need to divide the interval (a,b) in n equal subinterval, then we need divide the distance (d) between the endpoints of the interval and divide it by n. Then the width Δn of each subinterval is d/n.

We have the interval [-5,7]. The distance between the endpoints of the interval is

.

Now, we divide d by 4 and obtain

Then, Δn=3.

Now, to find the endpoints of each sub-interval, we add 3 from the left end of the interval.
