Find the domain of a function #shorts

The video tutorial explains how to solve an inequality involving variables and conditions. It begins by outlining the conditions for the inequality, then demonstrates the steps to solve it. The solution is visualized on a number line, showing the range of values that satisfy the inequality. Finally, the video concludes with an explanation of the final solution, highlighting the inclusion and exclusion of specific values.

Why must X be greater than zero in the given context?

• Because it is in the numerator

• Because it is in the denominator

• Because it is a variable

• Because it is a constant

What inequality represents the condition that X is less than 2?

• X ≥ 2

• X < 2

• X ≤ 2

• X > 2

How is the number line used to represent the range of X values?

• By marking values greater than 1

• By marking all values less than 1

• By marking all values greater than 2

• By marking values between 1 and 2

What does a filled dot on a number line indicate?

• The value is a variable

• The value is an estimate

• The value is included

• The value is not included

What does an open dot on a number line signify?

• The value is a constant

• The value is not included

• The value is an approximation

• The value is included
