(f-g) (3x) = 27x^3+12+2
Step-by-step explanation:
First lets write the following:
(f-g) (3x) = f (3x) - g (3x)
Now we need to find equivalent expression for f (3x) and for g (3x), we will obtaine them by evaluating 3x instead of x in every 'x' appearance.
Wi have>
g (3x) = - 27x^3+4
f (x) = 12x-2
Now, lets perfomr the desired operation.
f (3x) - g (3x) = 27x^3+12+2
