Question

Find the range if y = 3x + 12 for x = {0.4, 0.6, 1.8, 2.2}.
A. {1.2, 1.8, 5.4, 6.6}
B. {13.2, 13.8, 17.4, 18.6}
C. {12.4, 12.6, 13.8, 14.2}

Answer 1

just put x=0.4,0.6,1.8,2.2 in y=3x+12 and see what you get for y..that will be the range of y

Answer 2

once you put those values in find the max and the min of the y values, the range is from the min to the max.
