Answers:
Graph A is a function
Graph B is not a function
========================================================
Explanation:
To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"
If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.
A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.
Answer:
15
Step-by-step explanation:
y=21 x 5 = 105
x=3 x 5 = 15
Answer:
<u>448 cm³</u>
Step-by-step explanation:
Finding volume :
- V = LWH/2
- V = 1/2 x 14 x 8 x 8
- V = 7 x 64
- V = <u>448 cm³</u>
Answer:
A
Step-by-step explanation:
Since -8 < 0, we use the top equation which is x^2.
f(-8) = x^2
f(-8) = -8^2
f(-8) = 64
The situation "<span>the positive correction between the number of crimes in a city and the number of cars in a city" most likely affects causation. Causation is often defined as a "the causal relationship between the conduct and result." The concept mainly relies on a belief that one event causes the other.</span>
