2 Precise Definition of a Limit Let fbe a function deined on some open interval that contains the number a, except possibly at a itself. Then we say that the limit of fla) as r approaches a is L, and we write lim f)-L (x) = if for every number ε > 0 there is a number δ > 0 such that 0<lx-a |<δ If(x)-L| < ε if then For the limit 2x tii illustrate Definition 2 by finding values...

1. The definition of a limit says that lim f(x)=L means that for every & >o there exists a number 8 >0 such that if o < x-al<8, then f (x)-L<£. We have lim(x + 3x - 2) = 8. If < =0.01, find the largest possible value of that will satisfy the definition. Round your answer to the nearest ten-thousandth (that's four spots after the decimal point). If you're having trouble understanding the deltas and epsilons, that's normal. Another...

A graphing calculator is recommended. For the limit lim x → 2 (x3 − 4x + 7) = 7 illustrate the definition by finding the largest possible values of δ that correspond to ε = 0.2 and ε = 0.1. (Round your answers to four decimal places.) ε = 0.2 δ = ε = 0.1 δ =

State the steps for proving that lim f(x) - L xa to find a condition of the form Then, for any g>0, assume and use the relationship Let e be an arbitrary positive number. Use the inequality where depends only on the value of prove that between lim (x+1=0. Specify a relationship between...
