10-2(4+3x)
Someone help me pleas

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

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

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4
