Find the inverse of the equation y=x2+3

y =x^2 +3

to find the inverse interchange the x and y and solve for y

x = y^2 +3

subtract 3 from each side

x-3 = y^2

take the sqrt of each side

+-sqrt(x-3) =y

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
