Semester Exam PreCal (fall)

Front

What is the result of dividing (9x^2 + 6x) by 3x?

Back

3x + 2

Front

What is the RANGE of the graph represented by -3 ≤ y < 1?

Back

The range is the set of all possible y-values, which is -3 ≤ y < 1.

Front

Identify the point of discontinuity in the function f(x) = \frac{x+2}{(x-3)(x+2)}.

Back

The point of discontinuity is x = -2.

Front

Write the inequality in interval notation for the graph that includes -4 and excludes -1.

Back

[-4, -1)

Front

What is the DOMAIN of the function that is defined for x in (-3, 3)?

Back

The domain is (-3, 3).

Front

Define the term 'Domain' in the context of functions.

Back

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

Front

Define the term 'Range' in the context of functions.

Back

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

Front

What is a point of discontinuity?

Back

A point of discontinuity is a point at which a function is not continuous, meaning it does not have a defined value or has a break in the graph.

Front

How do you find the domain of a rational function?

Back

To find the domain of a rational function, identify values that make the denominator zero and exclude them from the set of real numbers.

Front

What does the notation [-4, -1) signify?

Back

The notation [-4, -1) indicates that -4 is included in the interval, while -1 is not included.
