Calculus Question
1) Evaluate lim ((1/x1) + (1/(x+1)) / x
x>0 Don't use derivatives for #1 2)Where is the function f(x) =  ln(x)+(sin(e^x)/x^2+5)  defined, and where is it continuous ? 3) Determine where the function f(x) = (x^2+5x+6)/(x+3) is discontinuous, and define a continuous extension g of f. 4) I KNOW THE ANSWER FOR THIS BUT DON'T KNOW WHAT IT IS ASKING FOR ? Suppose that x^26x3 <= f(x) <= sqrt(9x^2) on [0,3]. Give upper and lower bounds for lim x>0+ f(x) and lim x>3^ f(x) lim (x^2  6x  3) = 3 as x > 0+ lim v(9  x^2) = 3 as x >0+ 3 = f(x) = 3 lim (x^2  6x  3) = 12 as x > 3 lim v(9  x^2) > 0 as x > 3 12 = f(x) = 0 (What is the upper bound and lower bound ? I don't know that.) thanks....please answer these four questions perfectly. Only answer them if ur 100% sure.
