Evaluate the function f(x)=2x−2 , when x=−1 .−4
−3
0
4

Step-by-step explanation:

First option-->X=-1

2·(-1)-2=-4

Second option-->X=-4

2·(-4)-2=-10

Third option-->X=-3

2·(-3)-2=-8

Fourth option-->X=0

2·0-2=-2

Fifth option-->X=4

2·4-2=6

The last one is the only one positive

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

=

10
