Can someone help me, please??

Why would you want to get this

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
