Which shows the correct composition for finding (ƒ ° g) (x) ?

ƒ (x) = 4x

g(x) = 3x + 1

• (ƒ°g)(x) =4x(3x+1)

• (ƒ°g)(x) = 3(4x)+1

• (ƒ°g)(x) = 4(3x+1)

• (ƒ°g)(x) = 3x(4x)+1

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
