Functions Domain & Range Evaluate with Function Notation

Does graph represent a function? State the domain & range. Vertical line test - if a vertical line will only touch the graph at most 1 time – then the graph represents a function. Domain: how far left, how far right Range: how low, how high Included use [ ] Not included use ( )

Does graph represent a function? State the domain & range. Domain: (-4, 5] Range: [-3, 4) Function? Yes

Evaluate for the given value. The function name is F, and this function is in terms of x. Replace the variable with indicated value.

Evaluate for the given value.
