Front

Which piecewise function corresponds to the graph where f(x) = { -x+1 if x < 4; x if x ≥ 4}?

Back

f(x) = { -x+1 if x < 4; x if x ≥ 4}

Front

Define a piecewise function.

Back

A piecewise function is a function defined by multiple sub-functions, each applying to a certain interval of the domain.

Front

What is the angle of elevation?

Back

The angle of elevation is the angle between the horizontal line and the line of sight to an object above the horizontal.

Front

How do you find the distance to an object using angles of elevation?

Back

Use trigonometric functions, specifically tangent, to relate the angles of elevation to the distances.

Front

What is the formula for the tangent of an angle in a right triangle?

Back

tan(θ) = opposite/adjacent.

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input.
