4pts each] 9. Find the limit of the following if the limits exist. If not, explain x -3x+2 1) lim +4 r-1 11) lim 111) lim + 3x + 4 iv) lim :-*x-4 v) If 2x-15g(x)=x-2x+3, find limg(x)
Referring to the graphs given below, use properties of limits to find each limit. If a limit does not exist then state that it does not exist. y = f(x) y = g(x) lim f(x)= lim g(x) = f(x) x- lim x+0 g(x) lim lim g(x) = lim [f(x)+g(x)] = x-1 lim f(x) = lim g(x) = lim --+ f(x) h- h derivative of f(x) = 2x² + 3x is f'(x) = 4x +3. The steps are what count here!...
Let a, b, and c denote complex constants. Then use definition (2), Sec. 15, of limits to show that: (a) lim z -> z_0 (az+b) = az_0 + b; (limit as z approaches z not) (b) lim z -> z_0 (z^2 + c) = (z_0)^2 + c; (limit as z approaches z not) (c) lim z -> (1-i) [x+i(2x+y)] = 1+i; (limit as z approaches 1 minus i) Definition 2 from sections 15 basically states Epsilon delta informations. These are...

Sketch the following piecewise function and evaluate the limits, if they exist: if-ISX<11 x2 if x21 f(x) = x b) lim f(x) c) lim f(x) a) lim f(x)- x->-I lim / (x)- e) lim/(x)- d) x→1

Use properties of limits and algebraic methods to find the limit, if it exists. (If the limit is infinite, enter 'se' or '-co', as appropriate. If the limit does not otherwise exist, enter DNE.) 10 - 2x if x < 2 lim Rx), where f(x) = - X if x 22

e) lim x2-3x+2 *2-2x x-2 (x2-3x+2 x2 x2-2x yes, this is the SAME limit as in parte) Demonstrate ANOTHER (still algebraic/non-numerical) way to find this limit than you used in parte).
