Is g = {(1, 1), (2, 3), (3, 5), (4, 7)} a function? If g is described by g (x) = αx + β, then what value should be assigned to α and β.
Dear StudentGiven, g = {(1, 1), (2, 3), (3, 5), (4, 7)}It’s seen that every element of domain has a unique image. So, g is function.Now, also giventhat g (x) = αx + βSo, we haveg (1) = α(1) + β = 1α + β = 1 ........ (i)And, g (2) = α(2) + β = 32α + β = 3 ........ (ii)Solving (i) and (ii), we haveα = 2 and β =-1Therefore, g (x) = 2x - 1Thanks
