Find radius and interval of convergence.lim 3^x = 0 x--> -infinity, ε = 1/2, find smallest-magnitude N < 0Urgent numerical method Find the value around x ~ 1, which provides the equality of x ^ 3 + x - 1 = 0, by using the Newton-Raphson technique after checking the convergence criterion with a precision of 4 decimal places.
- Find all the ?-values at which the critical points occur of the function f(x)= 2x^3-8x^2+7x on the interval [0,3] (Give your answer in the form of a comma‑separated list. Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if there are no critical points.) x values where the critical points occur:There are 25 prime numbers less than 100. The Prime Number Theorem states that the number of primes less than x approaches p(x) ≈ x / lnx . Use this approximation to estimate the rate (in primes per 100 integers) at which the prime numbers occur when (a) x = 1000. (b) x = 1,000,000. (c) x = 1,000,000,000.pointwise convergence q help.
