RATL 3 | Lesson 1 | Practice (Rational Expressions)

 

Putting it all together

For the following rational expressions:

1) Determine the domain of the expression.

2) Simplify the expression, if possible.

3) Evaluate the expression for the values given.

a) \(\Large \frac{x^2+3x-4}{x^2-x-20}\), evaluate for \(x=-3,\, 0, \, 3\)

b) \(\Large \frac{x^2-25}{5x-x^2}\), evaluate for \(x=1, \, 3, \, 4\)

c) \(\Large \frac{x^2-16}{x^2-x-12}\), evaluate for \(x=-4, \, 0, \, 3\)
