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>

the side x is 15
bottom right angle is 31.61 degrees
other angle is 58.39 degrees
Answer:
3
Step-by-step explanation:
I say it is 3 because 2 * 3 = 6
6/2=3
I hope this helps you:)
7 over 32 you cant simplify it
Answer:
T(2, -7) = (4, -10)
Step-by-step explanation:
T(x, y) = (x + 2, y - 3)
T(2, -7) = (2 + 2, -7 - 3)
T(2, -7) = (4, -10)
