Question

May I ask for a handwritten answer/non-AI generated answer for this question since I really need a well-rounded explanation? Thank you!

3. For each statement, determine whether it is TRUE or FALSE. (Enter T or F in the middle of the box)
(a)
Let f be a function defined on R. If f2 is continuous at a, then f is continuous at a.
(b)
Let f, g, and h be functions defined on R and let a Є R. If
VxR, f(x)g(x) ≤ h(x),
⚫lima f(x) exists and lima h(x) = ∞,
then lima 9(x) exists or is oo.
Let f and g be functions defined on R and let a € R.
If lima f(x)g(x) = 0, then lima f(x) = 0 and lim→a 9(x) = 0.
