First to answer will mark braineist. no work nessacary!

lets check 0,4  put in 0 for x

4*0+4   =4  good

4 * 2^0  =4  good

4*0+8 =8  no good

(0+2) ^2 =4   good

for the next point we only need to check 3 functions

(1,8)

4*1+4   =8  good

4 * 2^1  =*8 good

4x+8   don't care since it didn't work for (0,4)

(1+2) ^2=8   good

for the next point we need to check 3 functions

(2,12)

4*2+4   =12  good

4 * 2^2  =16   no good

4x+8   don't care since it didn't work for (0,4)

(2+2) ^2=16  no  good

Choice A

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
