Answer:

x = 1

Explanation:

Remember that "f(x)" is kind of like saying "y." So picture the question like this: solve for x when y = 1. So let's substitute "1" for "y" (or f(x) in this case) like so into the given equation and solve for x:


1 = - 3x + 4 \\-3 = -3x\\x=1

So, x = 1. Please don't hesitate to ask any questions!
