△abc is reflected to form △a′b′c′ . the vertices of △abc are a(3, 1) , b(1, 5) , and c(6, 9) . the vertices of △a′b′c′ are a′(−1, −3) , b′(−5, −1) , and c′(−9, −6) . which reflection results in the transformation of △abc to △a′b′c′ ?

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

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

The revenue each season from tickets at the theme park is represented by t(c)=5x. the cost to pay the employees each season is represented by r(x)=(1.5)^x. examine the graph of the combined function for total profit and estimate the profit after four seasons
