1/ f(x) = ( -x) if x0 f(x) = 3-x if 0 = x3 f(x)= (x-3)^2 if x3 a. lim =? x-0 b. lim=? x-3 c. where is f(x) discontinuous?

1/ f(x) = (-x) if x<0

f(x) = 3-x if 0 =< x<3

f(x)= (x-3)^2 if x>3

a. lim =?

x->0

b. lim =?

x->3

c. where is f(x) discontinuous?

2/ use the Intermediate value Theorem o the given interval to show that there is a root of

Cos (√x) - e^x +2=0, (0,1)
