To simplify the expression 3√2 * √20, you can first simplify the square root of 20:
√20 = √(4 * 5) = √4 * √5 = 2√5
Now, substitute this value back into the original expression:
3√2 * √20 = 3√2 * 2√5 = 6√10
So, 3√2 * √20 simplifies to 6√10.Rate this question:

All Linear, Exponential and Quadratic functions have a range of 'all real numbers'
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Of the three types of functions listed, only the Linear function has a Range of 'all real numbers'.
(Remember, Range is the span of y-values for the function, lowest to highest.)
For an Exponential function, the highest or lowest y-value is limited by the asymptote.
For a Quadratic function, the highest or lowest y-value is determined by the y-coordinate of the vertex.Rate this question:

Only Quadratic functions have both an increasing and a decreasing interval.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. Quadratic functions have a single turning point, called the vertex, where they change direction from increasing to decreasing or vice versa. However, functions of higher degrees, such as cubic or quartic, can have multiple turning points, resulting in more complex patterns of increasing and decreasing intervals.Rate this question:

Only Linear functions have a 'constant' rate of change.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Linear functions graph to be a line, whereas Exponential and Quadratic functions graph to be curves.
Only lines have a 'constant' rate of change. Curves always have 'varying' rates of change.Rate this question:

ALL functions (linear, exponential, and quadratic) have an 'asymptote'.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
An 'asymptote' is a feature of Exponential functions ONLY. It is a horizontal line that an exponential curve
approaches but never touches.Rate this question:

The Table of Values for a Quadratic function will never show duplicated y-values.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Since the graph of a Quadratic function always has two sides that are reflections across the
Axis of Symmetry then each point on one side has the same y-value as it's reflective point on the
other side. Hence, the complete TOV for a Quadratic function will ALWAYS contain duplicated
y-values.Rate this question:

The Median of a dataset is a calculation that is affected by low or high (outlier) datapoints.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The definition of Median is the middle value of an ordered dataset. It is not a calculated value. Hence, it is NOT affected by high or low (outlier) datapoints. Rather, it is the Mean of a dataset that is affected by outliers, since the Mean is a calculated value of the average of the datapoints.Rate this question:

A 'marginal' frequency of a Two-way Frequency Table is a row or column total. Please note, however, that the bottom right corner cell of the table is considered to be the 'grand' total, and is NOT considered as one of the marginal frequencies.Rate this question:
