Question

Find the range if y = 3x + 12 for x = {0.4, 0.6, 1.8, 2.2}.

Answer 1

y = 3x + 12 x = {0.4, 0.6, 1.8, 2.2}.
y=3(0.4)+12
y= 13.2 <---- R

y=3x+12
y=3(0.6)+12
y=13.8 <--- R

y=3x+12
y=3(1.8)+12
y= 17.4 <--- R

y=3x+12
y=3(2.2)+12
y=18.6 <--- R

( I realllly hate solving with decimals! :(( lol )
