D 1,020÷15=68 (that's the equation and the answer)
(-1,4)(2,6)
slope = (6 - 4) / (2 - (-1) = 2 / (2 + 1) = 2/3 <==
Answer:
Yes this is a function because when doing the straight line test it doesn't touch it two or more times.
Answer:
$49.20
Step-by-step explanation:
<u>ANSWER</u>
It is not one-to-one function
<u>EXPLANATION</u>
A one-to-one function must pass the horizontal line test.
The graph described in the question looks like the one in the attachment.
A horizontal line drawn in red cuts the graph at more than one point.
Therefore the parabola shown facing up with a vertex
is not a one-to-one function.
