Determine wether the function is continuous or discontinuous at x = -2. If it is discontinuous, classify the discontinuity.

g(x) = (3x^3+24x^2+36x)/((x+1)(x+2))

g(x) is discontinuous at x = -2, with a removable discontinuity.

find the limit as x approaches 13 for the function 

f(x) = ((x-4)^1/2-3)/(x-13)

The limit as x approaches 13 for the function f(x) = 1/6

100

find the derivative of f(x) = 6x^3

the derivative of f(x) is f'(x) = 18x^2

100

Find the AROC of

y=−x^2 +x−1; [0,3]

y=−x2 +x−1; [0,3] = -2

100

Find the limit of g(x) when as f(x) and h(x) approach x=2

 f(x) = -1/3 x^3 + x^2 - 7/3

h(x) = cos(3.14/2 *x)

lim f(x) = -1

lim h(x) = -1

So, the squeeze theorem guarentees that the lim of g(x)  as x approaches 2 is -1

determine if f(x) = (4-x^2)^1/2 is continuous from [-2,2]


Yes, the function f(x) is continuous 

200

determine whether the function is continuous at x = 3

f(x){ (x^2-9)/(x-9) if x < 3

        9  if x =3

        x^2 -3 if x >3

yes the limit is a continuous function at x = 3

200

Find the derivative of 

f(x) = (1+ x^1/2)(x^3)

f'(x) = 3x^2 + 3x^1/2*x^2 + (x^2*x^1/2)/2

200

Find the AROC of 

y=2x^2 −2; [−1,2] 

y= 2x^2 −2; [−1,2] = 2

200

find the lim of f(x) as h(x) and g(x) approach -1

h(x) = -1/4 x^2 - 1/2 x

g(x) = 1/3 x^2 + 3/2 x +2/3

The lim of h(x) = 1/4 and the lim of g(x) = 1/3,

so the squeeze theorem does not guarantee that the limit of f(x), but if it does exist, it would be between 1/4 and 1/3
