Pre-AP Precalculus Fall Final Review

Front

What value should be excluded from the domain of the function?

Back

x = -5

Front

What type of function is represented by the graph?

Back

Neither odd nor even

Front

Describe the transformation of the equation y = -2|x-3|+3 from the parent function y = |x|.

Back

Reflected over x axis, vertical stretch by 2, right 3, up 3

Front

Given f(x)= x² + 25 and g(x)= x - 5, find (f+g)(x).

Back

x² + x + 20

Front

What is the domain of the graph?

Back

(-∞,∞)

Front

Define the domain of a function.

Back

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

Front

What is an even function?

Back

A function f(x) is even if f(-x) = f(x) for all x in the domain.

Front

What is an odd function?

Back

A function f(x) is odd if f(-x) = -f(x) for all x in the domain.

Front

What does it mean to reflect a function over the x-axis?

Back

To reflect a function over the x-axis, you multiply the output by -1, changing f(x) to -f(x).

Front

What is a vertical stretch of a function?

Back

A vertical stretch occurs when the output values of a function are multiplied by a factor greater than 1.
