What is the y-intercept of a graph?

Back

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

Front

Evaluate f(-5) if f(x) = 2x + 8.

Back

f(-5) = 2(-5) + 8 = -10 + 8 = -2.

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where b > 0 and b ≠ 1.

Front

How do you identify a linear function?

Back

A linear function can be identified by its constant rate of change and can be represented by a straight line on a graph.

Front

What does it mean for a mapping to be a function?

Back

A mapping is a function if every input is paired with exactly one output.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

How do you find the y-intercept from a linear equation?

Back

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

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has one output, while a relation can have multiple outputs for a single input.
