Eiko is wearing a magic ring that increases the power of her healing spell by \( 30 \% \). Without the ring, her healing spell restores \( H \) health points. Which of the following expressions could represent how many health points the spell restores when Eiko is wearing the magic ring? Choose 2 answers: A \( 0.7 H \) ( \( \frac{130}{100} H \) ( \( \left.\frac{3}{10}+1\right) H \)

Graph the parabola. \[ y=(x+2)^{2}+4 \] Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.
