I need to find the inverse of x^2-7,x is greater than or equal to 0. I also need to graph it.

y =f(x) = x^2-7

x= f^-1(y)

y+7 = x^2

x = (y+7)^1/2

f^-1(y) = (y+7)^1/2

f^-1(x) = (x+7)^1/2

for x> -7 or x = -7

the graph will be straight line having positive slope.

regarding any doubt let me know
