Answer:
f(x) = 3ex - e
Step-by-step explanation:
In this equation we have basically the times e by 3x and -1
so first let's do e times 3x
here...
e X 3x = 3ex
so let's rewrite the equation
3ex - 1
now we times e by 1. (Note - Negative sign stays)
3ex - 1e
we don't have to write 1e cause 1e = e, they are the same.
Therefore the answer is 3ex - 1e

To solve this equality we are going to use
the <span>
division property of equality, which says that you can divide both sides of the equality by the same number; notice that the number in question cannot be zero since you cannot divide by zero. In our case we are going to divide both sides by 4.5 to get rid of the 4.5 that is multiplying </span>
