What I Have Learned:
Read carefully and answer the items that follow.
Directions: Tell whether the following statements are true or false.
1. The independent variable depends on the dependent variable.
2. The dependent variable changes only in response to the independent
variable
3. Salary is an independent variable because it controls the number of
hours that one works.
4. The height of a plant is dependent on the number of years it grown.
5. In a given function, the domain is the set of acceptable inputs while the
range is the set of acceptable outputs.
6. We can use any value for the domain.
7. In a set of ordered pairs, the abscissas are the domain and the
ordinates are the range.
8. In a rational function, S(x) the domain is the set of real numbers
not equal to the number that would make the denominator zero.
9. In a rational function, f(x) the range is the set of real numbers
except zero.
10. In a radical function, f(x) = 2 * + 1the domain is the set of real
numbers greater than or equal to 0.
11. The range of the function f(x) = 2 x + 1 is the set of real numbers less
than or equal to 2.
12. The range of the function f(x) = 1 - 3x is the set of real numbers.
13. The range of the function f(x) = -2(x - 3)2 is the set of all real number
greater than or equal to zero
14. To find the domain of a function described by the graph, we look
horizontally from left to right, look for breaks or gaps on the graph,
where it begins and where it ends.
15. To find the domain of a function described by the graph, we look
vertically up and down, look for breaks or gaps on the graph, where it
begins and where it ends.
