Which equation can be simplified to find the inverse of y = x2 – 7?

a: x=y ^ 2 – 1/7

b: 1/x = y^2 – 7

c: x = y^2 – 7

d: –x = y^2 – 7

Answer:- a: x=y ^ 2 – 1/7

The correct answer is ‘x=y^2 – 1/7.’ To find the inverse of a function, we swap the position of the variables and solve for the new variable. In this case, the function is y = x^2 – 7. So, we swap the position of x and y to get x = y^2 – 7. We can then simplify this equation to get x = y^2 – 1/7.
