Answer:
functions: A, C; non-functions: B, D
Step-by-step explanation:
A relation is not a function if any input value (x) maps to more than one output value (y).
On a graph, we apply the "vertical line test." If any vertical line intersects two or more points on the graph, it is not a function. We say it fails the vertical line test. The bottom graph (D) fails the vertical line test, so is not a function.
On a mapping, such as figure B or C, any input (x-value) that is the source of two or more arrows means the relation is not a function. The map of B is not a function.
The other choices (A and C) show a functional relation.
Answer:
B. All real numbers
Step-by-step explanation:
Given:
The function is given as:
Domain is the input to a function represented by the values of 'x'. The domain defined a function's output which is also called as the range of the function.
The above function is an example of an exponential function. An exponential function is of the form:
Where, 'a' is any number greater than 0.
Here,
The domain of an exponential function is not restricted and includes all real values. But, the range of an exponential function is always a positive number.
Hence, the domain of the given exponential function is not restricted and include all real numbers. So, option B is correct.
A graph of an exponential function is attached to support the answer.
Can you show all of the numbers please so i can see it
Answer:
16%
Step-by-step explanation:
Given data
Initial cost= $9
final cost= $7.56
Required
The percent discount
Step two
Percent discount= final-initial/initial *100
Percent discount= 9-7.56/9 *100
Percent discount=1.44/9 *100
Percent discount=0.16 *100
Percent discount=16%
Hence the percent discount is 16%
