Plug in (1) for x. It will look like this:
f(1) = 4 *(1)  3
four times negative 1 equals negative 4, so...
f(1) = 4  3.
negative four minus three is easiest to figure out with a number line...it equals negative seven. So:
f(1) = 7. And you're done!
here is another one i have no idea how to do. if f(x)=4x3 how do I find f(1)
4(1)  3
four times negative 1 is negative 4.
So what's
43
?
