I need help

[whitneytatewright]

The question is Does the parabola y=2x³-13x+5 have a tangent whose slope is -1? If so, find an equation for the line and the point of tangency. Help?

First, it's not a parabola. Did you mean "x^2"?

Second, all tangents at a point 'c', have slope 3c^2-13 and pass through the point (c, 2c³-13c+5)

Of course, if you meants x^2, you must start over and show your work.
