PLZZZ HELP DUE IN 5 MINS

Mathematics
1 answer:
iris [78.8K]2 years ago
4 0

Answer:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)}

Step-by-step explanation:

recall that for a function to be valid, every input must give one and only 1 output. (i.e every x-ordinate must have only one unique corresponding y-ordinate)

I have highlighted in bold and underlined the entries for each of the other choices where an x-value gives more than one possible y-value, hence these are not functions. only the first option satisfies this condition:

{(2, 9), (5, 9), (1, -6), (-5, 5), (2,9), (5,9), (1,−6), (−5,5)} Every x-value has a unique y-value, so it is possible that this is a function.

{<em><u>(6, 6)</u></em>, <em><u>(6, 8)</u></em>, (-8, -7), (-3, -8), (6,6),(6,8),(−8,−7),(−3,−8)}  (not a function)

{(1, 8), (9, -3), <u><em>(7, -4)</em></u>, <u><em>(7, -6)</em></u>, (1,8),(9,−3),(7,−4),(7,−6)} (not a function)

{<u><em>(-5, -1)</em></u>, (-3, -7), <u><em>(-5, 3)</em></u>, (-7, -4), (−5,−1),(−3,−7),(−5,3),(−7,−4)} (not a function)

Please help i need answer for test
Korvikt [17]

Answer:

He did the complete opposite of what he needed to do

Step-by-step explanation:

The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.

Cause otherwise, what he did here is to find the y - intercept
