Zeros
Learn zeros in Grade 9 math — Explanation Zeros are just a cool math name for where a graph crosses the x-axis. Part of Sequences and Special Functions for Grade 9.
Key Concepts
Property The zeros of a function are its x intercepts or solutions. Explanation Zeros are just a cool math name for where a graph crosses the x axis. They're called 'zeros' because at these exact spots, the function's y value is zero. Think of it as the graph's touchdown point! Examples If a graph crosses the x axis at $x = 2$, then $ 2$ is a zero of the function. The function $y = x^3 8$ has a zero at $x = 2$, because $2^3 8 = 0$. Finding the zeros of $y = x^3 + 1$ is the same as solving the equation $0 = x^3 + 1$.

Why is 'Zeros' an important Grade 9 math skill?
Common mistake tip: A very common mix-up is confusing zeros (x-intercepts) with the y-intercept.. - To find the y-intercept, you set $x$ to 0.
