Which relations are functions?

Mathematics
1 answer:
pychu [463]3 years ago

For a relation to be a function every x value will have a single y value.

The first one has two x values of -2 but their y values are different so can’t be a function.

The second one has two 10’s with different y values so isn’t a function.

The 3rd one has 1 and -1 with the same y value, so isn’t a function.

The correct answer is the 4th choice

Which of the following has the same value
ioda

When solving (-2)5(-2)-8, you would first, following PEMDAS ofcourse, multiply -2 and 5, getting -10. Then you would multiply -2 and -10, which would be positive 20. Lastly, you would subtract 8 from 20, which equals 12.

I cannot find an answer within the options you gave me, but I am 100% sure that (-2)5(-2)-8 equals 12.

Hope this helped in some way! Please mark brainliest! Thank you v much! :)

Any one that knows this please help thanks!

If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)
