Is there any real number exactly one less than its cube intermediate value theorem?

≈ 1.32471795725...

Explanation:

If x is one less than its cube, then

x = x³ - 1,

x³ - x - 1 = 0

so f(x) = ? would be an appropriate (continuous) function to apply the Intermedate Value Theorem on some appropriate interval to see if it takes on the value 0 in that interval.

f(x) = x³ - x - 1

For large x the left hand side is positive, for x = 0 it is negative. The root can be calculated exactly, it is given by:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
