Study Notes
Factoring
- The expression (10x^2 - 7x - 3) can be factored into ((10x + 3)(x - 1)).
Domain
- The domain is a set of x-values, which in this case is ({-2, 0, 2}).
Functions
- A function uniquely maps each x-value to a single y-value, exemplified by pairs like ((2, 3), (3, 4), (4, 2)).
Parabola
- A parabola has a vertex that represents its extreme point (maximum or minimum), while the x-intercepts are known as zeros.
Function Notation
- (f(x)) denotes a function with output (y), where (f(2)) requires solving for y when (x = 2).
Rule of One
- Any number raised to the power of 1 remains unchanged, while 1 raised to any power results in 1.
Product Rule
- When multiplying two expressions with the same base, their exponents can be added together.
Power Rule
- When raising a power to another power, multiply the exponents.
Quotient Rule
- Dividing two expressions with the same base entails subtracting the exponents while retaining the base.
Zero Exponent Rule
- Any non-zero number raised to the zero power equals 1.
Negative Exponents
- A nonzero number with a negative exponent equals the reciprocal of that number raised to the opposite positive exponent (e.g., (4^{-2} = \frac{1}{4^2})).
