Draw a number line and place a dark dot at x=(2). Place a circle at x=0.
Connect the circle at x=0 to the dot at x=2 with a line segment.
Not knowing what your M means, I can't go any further here helping you. Please explain where M came from and what it means.
Answer:
No.
Step-by-step explanation:
All numbers that are able to be represented as fractions with whole numbers are rational.
Answer:
The answer to 75 - ( 8 + 45 ÷ 3 ) × 2= 29
A relation is (also) a function if every input x is mapped to a unique output y.
In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:
- The first graph is exactly a vertical line, so it's not a function.
- The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
- The third graph is not a function, because you can draw vertical lines that cross the graph twice.
- Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
- The fifth graph is a function, because every vertical line crosses the graph once
- The last graph is a function, although discontinuous, for the same reason.
