please show or explain work if possible. :) Given the following functions:
f(x)=-3+4
g(x)=-2/3 x+9
h(x)=3x^2-6

1. Find (f•g)(-5)
2.Find (g•h)(x)
3.Find (h•f)(x)

4.What is the inverse of the function f(x)=2+(2/3x)

What is the 12th term of b(n)=-4-2(n-1)

Mr.walker is looking at the fundraiser totals for the last five years , how does the mean of the totals compare to the median?

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
