Final answer:

To find the equation of the line that is tangent to both y = 1/x and y = -x², set the two equations equal to each other and solve for the x-values of the points of intersection. Use the slope formula and point-slope form to find the equation of the line.

Step-by-step explanation:

To find the equation of the line that is tangent to both y = 1/x and y = -x², we need to find the points where the two curves intersect. To do this, set the two equations equal to each other:

1/x = -x²

Solve this equation to find the x-values of the points of intersection.

Once you have the x-values, substitute them back into either equation to find the corresponding y-values.

Now that you have two points on the line, you can use the slope formula to find the slope of the line:

m = (y₂ - y₁) / (x₂ - x₁)

Finally, use the point-slope form of a linear equation to find the equation of the line:

y - y₁ = m(x - x₁)
