Question

Does the equation y²+x =1 represent a function y in terms of x.​

Answer 1

Answer:

NO

Step-by-step explanation:

y^2+x=1

=> y^2=1-x

=> y= plus or minus the sqrt of 1-x

=> y= + sqrt(i-x)      (or)       y= - sqrt(1-x)

For one value of x we have two values of y

Therefore , it is not a function
