For the first part of the question we have two functions
If the expression refers to the multiplication of f and g, then:
So we multiply the function f(x) with the function g(x)
For the second part we have the functions:
We wish to find (f - g) (x). We know that
its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Hope this helps!
