What is the critical value, t*, for c = 0.95 and n = 16?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

I'm confused on this could anyone me and show me what i need to do to solve it.
