A function is symmetric over the y-axis if


f(-x) = f(x)
- It's an even function


A function is odd if


f(-x) = -f(x)
- It is symmetric over the origin


A function is symmetric over the origin if


f(-x) = -f(x)
- It is an odd function


f^-1(f(x))


x

,f(n) = m, f^-1(m) = ___


n



leading coefficient


The coefficient of the term with the highest degree (leading term)


Solve an inequality with an absolute value


1. Isolate the absolute value
2. Solve for a + other side
3. Solve for a - other side AND flip the inequality

, Complex zeroes


When solving for all the zeroes, there will be a negative under the
square root. Replace it with i
- Its conjugate is ALSO a zero


Number of zeros of a polynomial


= the exponent of the leading term (the highest exponent)
- some can be imaginary and unseen on the graph


Complex conjugate


Complex numbers: a+bi and a-bi
- If a function has a zero at a+bi, it ALSO has a zero at a-bi


Multiplicity of a zero


Number of times a zero's factor occurs in a polynomial
- If odd, the line passes through that zero
- If even, the line will be tangent to the x-axis (bounce off) at that zero
