Answer:2000
Step-by-step explanation:I think
X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
The answer is (3+5i)-(2+i)
Switch where the x and y are, then solve for y. f(x) = y.
x = 3y^2 + 6
x-6 = 3y^2
(x-6)/3 = y^2
f^-1(x) = y = sqrt((x-6)/3)
