Moderate -0.5 This is a straightforward area-between-curves question requiring students to set up and evaluate ∫₋₂² (19 - (x⁴ + 3))dx. The symmetry simplifies the calculation, and integrating x⁴ is basic C2 content. It's slightly easier than average because the intersection points are given, the integrand is simple, and no problem-solving is needed—just direct application of the standard method.

The diagram shows the curve \(y = x ^ { 4 } + 3\) and the line \(y = 19\) which intersect at \(( - 2,19 )\) and \(( 2,19 )\). Use integration to find the exact area of the shaded region enclosed by the curve and the line.
