Until now, given a function <span>f(x)</span>, you would plug a number or another variable in for x. You could even get fancy and plug in an entire expression for x. For example, given <span>f(x) = 2x + 3</span>, you could find <span>f(y2 – 1)</span> by plugging<span> y2 – 1</span> in for x to get <span>f(y2 – 1) = 2(y2 – 1) + 3 = 2y2 – 2 + 3 = 2y2 + 1</span>.
In function composition, you're plugging entire functions in for the x. In other words, you're always getting "fancy". But let's start simple. Instead of dealing with functions as formulas, let's deal with functions as sets of<span> (x, y)</span><span> points </span>

Answer:
233.3 repeating mg
Step-by-step explanation:
Your teacher was really kind to give you the equation.
9x=2100
divide both sides by 9
we get x= 233.3 repeating mg
I’m timed on this I need help as well
A(n)=3n+5
You add 3 to each number so it’s the rate
5 is the initial value. 8-3=5
