I think first one
hope it will help you
but one thing I should say that in our computer functioning is so easy
Answer:
The correct answer is - All functions have a dependent variable
Step-by-step explanation:
Answer:
First option: All functions have dependent variable (At least)
Second option: All functions have an independent variable.
Fifth option: A horizontal line is an example of a functional relationship.
Step-by-step explanation:
STEP-1
By definition, a relation is a function if each input value has one and only one output value.
A function have a at least a dependent variable and an independent variable. For example, given a function:
The dependent variable is "y" and the independent variable is "x".
STEP-2
The Domain of the function is the set of possible input values and the Range is the set of possible output values,
Vertical lines have undefined slope. Since the value of "x" never changes, a vertical line is not an example of a functional relationship.
In the case of Horizontal lines, for any x-value you get the same y-value. These are called "Constant functions".
STEP-3
Based on this, the following statements are true:
All functions have a dependent variable (At least).
All functions have an independent variable.
A horizontal line is an example of a functional relationship.
Check all that apply.
All functions have a dependent variable.
All functions have an independent variable.
