What is the range of y = x^2 − 1 , given a domain of {–2, –1, 0, 1, 2}? R : y ≥ − 1
R : − 1 ≤ y ≤ 3
R : { − 1 , 0 , 3 }
R : { − 5 , − 2 , − 1 , 0 , 3 }

10 * 563.67 = 5636.7

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
