A particle moves along the x-axis so that at time t > 0 its position is given by X(t) = -5t4 + 30t^2. Determine all intervals when the speed of the particle is
increasing

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2
