@emilys819 whenever you have two functions say \[f*(g(x)) \] this means that you have two composite functions. If I remember this correctly, this means that you compute the value of x for whatever function is in the inside, then you compute the value for the other function. Let's look at this first:
\[f(*g(x))= outside (inside) \]
You plug in a value x in whatever function is on the inside and you'll get a number.
you take that number and plug it into the function on the outside say f(x).
first we identify our functions:
f(x) = -4x+7
g(x) = 2x-6
f*(g(x)) in this case our x value is one, so we plug in one to g(x) and we will get a number.
g(1) = 2(1)-6 = 2-4 = -4
so g(1) gives us -4 as our value.
we take this and we plug this into f(x) now
f(4) = -4(1)+7 = -4+7 = 3
so our answer for this is 3.
the answer is not 3, ah no, wait sorry.. we had -4 from the f(1) we take that number -4 and plug it into g(x) g(-4) -4(-4)+7 = 16+7 = 23
