Regents Exam: Algebra I August 2016 (Problem 5 of 37)

The video tutorial explains how to evaluate a function F of N by systematically testing given options to determine which yields a true statement. The process involves substituting values into the function, simplifying expressions, and comparing results to the expected outputs. The tutorial demonstrates this method with two options, ultimately finding that option 2 is correct.

What is the primary task when given the function F of N?

• To find the value of N that makes the function zero.

• To rewrite the function in a different form.

• To determine which option yields a true statement.

• To graph the function for different values of N.

What is the first step in evaluating the function with a given input?

• Rewrite the function in terms of another variable.

• Find the derivative of the function.

• Substitute the input value into the function.

• Graph the function.

When evaluating option one, what was the input value used?

• -2

• 0

• 3

• 5

What was the conclusion after evaluating the function with the input from option one?

• The output matched the expected result.

• The output did not match the expected result.

• The function was undefined for this input.

• The input was not valid for the function.

Which option was found to yield a true statement after evaluation?

• Option 4

• Option 3

• Option 1

• Option 2
