Is the relation a function? Yes or No? (4,5),(4,-7), (4,2), (4,0), (4,9)

No it's not a function

Step-by-step explanation:

When the domain repeats either once or more, it's never a function

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
