Function Evaluation and Range Analysis

Graphing linear functions

Solving quadratic equations

Understanding imaginary numbers

Finding the domain and range of a function

f(x) = x^2 + 2

f(x) = √(2 - x)

f(x) = 2x - 3

f(x) = x/2

By setting x = 0

By setting x^2 = 2

By setting 2 - x = 0

By setting 2 - x > 0

It results in a division by zero

It makes the function undefined

It results in a negative number under the square root

It makes the function non-linear
