For what value of t is H(t) = 4?

Back

t = 1

Front

Does this mapping diagram represent a function?

Back

How to determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a linear function?

Back

A function that graphs to a straight line, typically in the form f(x) = mx + b.
