Day 3 Algebra 1 EOC Review

Front

What is a function?

Back

A function is a relation in which each input (x-value) is associated with exactly one output (y-value).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, typically written as (x, y).

Front

What does the vertex of a parabola represent?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on its orientation.

Front

How do you identify a function from a set of ordered pairs?

Back

A relation is not a function if any x-value is repeated with a different y-value.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

Front

What is an exponential function?

Back

Front

Back

The graph is a parabola that opens upwards with its vertex at the origin (0,0).

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

Back

This represents a horizontal shift left by 2 units and a vertical shift up by 3 units.

Front

What is the significance of the base in an exponential function?

Back

The base determines the rate of growth or decay of the function; if the base is greater than 1, the function grows, and if it is between 0 and 1, it decays.
