The slope of the tangent line that touches the curve at is .

  1. Verify this is reasonable by sketching the function and drawing a tangent line to the curve at .

    Upward parabola, vertex at (0, comma 7), with highlighted point in first quadrant, labeled A = (2, comma question mark).

  2. Use the information above to write the equation of the line tangent to the curve at x = 2.

    Use point-slope form.
