Composition of Functions
Master Composition of Functions in Grade 10 math. ### Property If and are functions, the composite function uses the output values from as the input v.
Key Concepts
Property If $f(x)$ and $g(x)$ are functions, the composite function $f(g(x))$ uses the output values from $g(x)$ as the input values for $f(x)$. The composition is written as $f(g(x))$ or $(f \circ g)(x)$. It models a multi step process where the output of one function becomes the input for the next.
Let $f(x) = 4x+3$ and $g(x) = x^2$. Then $(f \circ g)(x) = f(g(x)) = f(x^2) = 4(x^2) + 3 = 4x^2 + 3$.
Let $f(x) = \sqrt{x}$ and $g(x) = x 7$. Then $(f \circ g)(x) = f(g(x)) = f(x 7) = \sqrt{x 7}$.

Why is Composition of Functions important for Grade 10 students?
This video breaks down a key exponent shortcut: the Power of a Power Rule. Think of it like this: if you have a bundle of items (like a power, ), and then you get more of those exact same bundles (like raising it to another power, ), you just multiply to find the total! So when you see a power...
