Please can someone help me with finding the Domain D of the mapping g :(2x^2) -1 if R={1,7,17} is the range and g is defined on D

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
