Given f (x) = 6x+2 and g (x) = x^3 which of the following are true? check all correct answers

1. f (x) x g (x) = 6x+2x^3

2. f (x) x g (x) = 6x^4+2x^3

3. f (1) x g (3) = 72

4. f (-1) x g (2) = - 32

F (x) * g (x) = (6x+2) x³=6x⁴+2x³ Correct answer is 2.

f (1) = 6*1+2=8

g (3) = 3³=27

f (1) * g (3) = 8*27=216

f (-1) = 6 * (-1) = - 6

g (2) = 2³=8

f (-1) * g (2) = - 4*8=-32

f (-1) * g (2) = - 32 Correct answer 4.
