Answer:
all real numbers
Step-by-step explanation:
The domain is the possible input values, or in this case, the values that x can be
For this graph, x can be any value, so x is all real numbers, the domain is all real numbers
Answer:
$5
Step-by-step explanation:

The item is discounted by $5 per week.
<span>We define
day--------------------------X
hockey cards away ------------f(X)
</span><span>He gives 2 cards away ----------------on day 1----------f(X)=2 X=1
</span>He gives 4 cards away ----------------on day 2----------f(X)=4 X=2
He gives 8 cards away ----------------on day 3----------f(X)=8 X=3
the sequence of cards away 2,4,8,16,32,64,128,256,512,1024
f(x) = 2**(x)
The answers are
D <span>Each day corresponds to a unique amount of hockey cards in this sequence.</span>
And B <span>The graph of this sequence would pass the vertical line test.
Each element of the Domain (X = day), relates to a single value of f(x) = number of hockey cards
That is, every value of X must have only one corresponding value of f(x)
(One value of y, for each input X)
This can also be checked by using the vertical line test.
If we plot f(x) and we draw vertical lines in the curve, we can verify that at every input the line intersects only one point of f(x)</span>
Answer:
The simplest form is 1/20
Answer:
-12
Step-by-step explanation:
? + 3 = -9
Subtract 3 from -9
-9 - 3 = -12
? = -12
