Topic 3 (Functions)

What is an initial value?

• The slope of a line

• A relation in which each input, or x-value, has exactly one output, or y-value

• The value of the output when the input is 0, or the y-intercept of the graph of a line.

• A function whose graph is not a straight line

• A period of time between two points of time or events

Mark has a $100 gift card to buy apps for his smartphone. Each week, he buys one new app for $4.99.

Which equation would represent the relationship between the amount left on the card (y) over time (x).

• y = 100x + 4.99

• y = 100x - 4.99

• y = 100 - 4.99x

• y = 100 + 4.99x
