Simplify: $$\frac{8-i}{-6+2i}$$

To simplify, multiply the numerator and denominator by the conjugate of the denominator: $$\frac{(8-i)(-6-2i)}{(-6+2i)(-6-2i)}$$ .

Rewrite log 5 25 = 2 in exponential form.

The exponential form is $$5^2 = 25$$ .

What is the quadratic formula?

The quadratic formula is used to find the roots of a quadratic equation and is given by: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ .

Explain the concept of a function. What are its components?

A function is a relation that assigns exactly one output for each input. Its components are the domain (set of inputs) and the range (set of outputs).

What is the difference between a rational and an irrational number?

A rational number can be expressed as a fraction $$\frac{p}{q}$$ where $$p$$ and $$q$$ are integers and $$q \neq 0$$ . An irrational number cannot be expressed as a simple fraction.

What is the definition of a polynomial?

A polynomial is a mathematical expression consisting of variables raised to whole number powers and coefficients, combined using addition, subtraction, and multiplication.

What does it mean for a function to be 'one-to-one'?

A function is one-to-one if it assigns different outputs to different inputs, meaning no two different inputs produce the same output.

What is the significance of the discriminant in a quadratic equation?

The discriminant, given by $$b^2 - 4ac$$ , determines the nature of the roots: if positive, there are two distinct real roots; if zero, one real root; if negative, two complex roots.

Define 'asymptote' in the context of graphing functions.

An asymptote is a line that a graph approaches but never touches or crosses, indicating the behavior of the function as it tends towards infinity.

What is the relationship between exponential and logarithmic functions?

Exponential functions and logarithmic functions are inverses of each other. If $$y = b^x$$ , then $$x = \log_b(y)$$ .
