Lesson of the week
Algebra
From the study guide Functions: domains and transformations
Study guide for Grades 10 to 12: domain restrictions and function notation; 2 worked examples and 4 practice questions. Over real numbers, denominators cannot be zero and even-root inputs must be nonnegative.
- Domain restrictions: Over real numbers, denominators cannot be zero and even-root inputs must be nonnegative.
- Function notation: f(x) denotes an output, not f multiplied by x.
- Example: For f(x) = 1/(x − 4), which input is excluded? Answer: 4.
