How do I apply the distributive property to create an equivalent expression for 4(x - 2 + y)

Is the following relation a function? x y 1 4 −1 −2 3 10 5 16 yes no

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

I’m still confused on how to work the percentages
