This is similar to Try It #1 in the OpenStax text. Use Figure 1 above to determine the local behavior and end behavior for the reciprocal squared function f(x)=1x2 . Use arrow notation. To enter ∞, click on the ∞ button and then on the ∞ choice. To enter -∞, type a minus sign and then enter ∞. Local behavior: As x→ − ,
