i have 3 calculus questions: 1)...

i have 3 calculus questions:

1) what values of x would create discontinuity and determine if is removable or not

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

2)evaluate the indicated limit, if necessary, change the form of the function

((x^3)/(3x^3 + 2))

x -> infinity

3) find the equation of the tangent line to the function. from first principal

f(x) = 2x^2 + 7x + 1, at x =2
