For in GOD we live, and move, and have our being.
 Acts 17:28
The Joy of a Teacher is the Success of his Students.

For ACT Students
The ACT is a timed exam...$60$ questions for $60$ minutes
This implies that you have to solve each question in one minute.
Some questions will typically take less than a minute a solve.
Some questions will typically take more than a minute to solve.
The goal is to maximize your time. You use the time saved on those questions you
solved in less than a minute, to solve the questions that will take more than a minute.
So, you should try to solve each question correctly and timely.
So, it is not just solving a question correctly, but solving it correctly on time.
Please ensure you attempt all ACT questions.
There is no "negative" penalty for any wrong answer.
For JAMB and CMAT Students
Calculators are not allowed. So, the questions are solved in a way that does not require a calculator.
For each of these relations:
(1.) Determine whether the relation is a function or not.
(2.) If it is a function, specify the kind or type of function.
(3.) Write the domain of the relation in set notation.
(4.) Write the domain of the relation in interval notation.
(5.) Write the range of the relation in set notation.
(6.) Write the range of the relation in interval notation.
NOTE: We are concerned with only real numbers.
Let: $D$ = domain; $R$ = range
From Questions (6.) through the rest of the questions in this section; ask this question:
Domain: What are the values of the input, $x$ that will not give any output, $y$?
Remove those values.
The set of all the input values that will give results when those input values are substituted in the functions is the Domain
Range: What are all the likely results that could be got from all those input values?
The set of all those output values that could be got when those input values are substituted in the functions is the Range
Give students some input values for each relation and ask them to calculate the output values
What will be the output values for certain input values?
Also, give students some output values and ask them to calculate the input values.
What input values will give certain output values?
