The "parent function" is y = (log to the base 2 of) x
The domain of this function is (0, infinity) (all real numbers greater than zero).
The range of this function is the same as above.
If you replace "x" with "x+1" in the parent function, the associated graph will look the same as that of the given function, EXCEPT that it will be translated by 1 unit to the left.
After this has happened, that "-3" will shift the entire new graph downward by 3 units.
Since, it is not given how many coins did Erica buy at the coin show, so, we can suppose that Erica bought "n" coins from the coin show.
Now, we know that Erica already had 6 coins in her coin collection before she went to the coin show and bought the "n" coins.
Therefore, the total number of coins that Erica will have in her possession after buying "n" coins from the coin show will be 6+n.
Answer:
B.
Step-by-step explanation:
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
