Let d = domain and r = range for short-hand purposes
13. d: [ - 4, 4] r: [- 2, 2]
14. The right most point does not have a label under it so I'm going to assume it's both a 5 and an infinity
If it's a 5 then:
d: [ - 4, 5] r: [ - 2, 4]
If it's an infinity then:
d: [ - 4, ∞) r: [- 2, 4]
The circles are closes meaning you include them in the function f so you must use the brackets and parentheses exactly how they are used above.
False
When rounding, five or more will make the value go up.
Your change value is a 6 so the dollar value should be $45
Step-by-step explanation:
In mathematics, a function is a mapping from set A to a set B that has a unique output for any given input. “Operators” or “operations” are typically defined as a special type of function.
The true statement is the one in the fourth option:
"UV is perpendicular to AB and UV is parallel to ZY"
<h3>
Which statement is true?</h3>
Here we have some statements about the lines that we can see on the image.
For example, the first statement can be translated to:
"Line AB is parallel to line UV, and line AB is parallel to line WX"
This is false, because two parallel lines never do intersect and in the graph we can see that AB intersects the line UV, so these lines are not parallel.
Now, one of these statements is only true if both parts are true.
Now that we can read the statements, the one that is true is the last one:
"UV is perpendicular to AB and UV is parallel to ZY"
By looking at the image we can see that this is true, thus, the fourt option is the correct one.
