Again, to tell if a relation is a function, they must pass the vertical line test, draw lines down the x axis and make sure the line does not intercept the relation twice or more.
The correct answer is the one on the bottom left. You can draw any vertical lines down the graph and it would not intercept two points or more at once
In order to answer, you need to sketch the given exponential curves and straight lines and ask yourself if and when do they cross each other:
a) 2ˣ + 1 is an esponential curve with base >1 shifted up by 1;
-3x + 6 is a straight line with negative slope, shifted up by 6;
They cross each others only one time.
b) 3ˣ - 3 is <span>an esponential curve with base >1 shifted down by three, thus it can be negative;
2x - 2 is </span><span> a straight line with positive slope shifted down by 2;
They cross each others twice.
c) -4</span>ˣ - 1 is <span>an esponential curve with base >1 flipped over the x axis and shifted down by 1;
3</span>⁻ˣ - 2 is an esponential curve with base <1 ( 3⁻ˣ = (1/3)ˣ )and shifted down by 2;
They never cross each others.
Therefore the correct rder is:
-4ˣ - 1 = 3⁻<span>ˣ - 2
</span>-3x + 6 = 2<span>ˣ + 1
</span>3<span>ˣ - 3 = 2x - 2</span>

Answer:
(-7, -11)
Step-by-step explanation:
The hole is at x=-7. The left- and right-limits at that point are -7-4 = -11. So, the coordinates of the hole are (-7, -11).
Answer:
Mean = 10.181818181818181818181818
Median = 10
Mode = 8
Range = 13 - 8 = 5
Step-by-step explanation:
MEAN 8+8+8+9+9+10+10+12+12+13+13 = 112/11=10.1818 forever.
MEDIAN 8 8 8 9 9 10 10 12 12 13 13
count five in both directions
MODE most numbers in a number scheme
RANGE highest number minus lowest number.
