If an arithmetic series has a1 equals=44, d equals 5, and n=24, what is sn?

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

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Which inequality has a dashed boundary line when graphed ?
