Question

Which equation is a function of x? x = 5 x = y squared + 9 x squared = y x squared = y squared + 16

Answer 1

x² = y is a function of x.

Step-by-step explanation:

If you input a value of x then we get the output f(x) = y, which is the function of x.

x = 5 [This is not a function. Because function notation is f(x)]

x = y² + 9 [this is not a function of x]

x² = y

=> y = x²

=> f(x) = x²  

This is a function of x.

x² = y² + 16 [it has no function notation. So, this is not a function]

Hence, x² = y is a function of x.
