MODELING REAL LIFE An obstacle course needs a
new piece made in the shape of a triangular prism
with an equilateral triangle for a base. The side length
x (in feet) of the base and the height y (in feet) of the
prism are related by the inequality y> x² + 1. The
piece has the following additional constraints.
• The height must be no more than 7 feet greater than
the side length of the base.
• The side length of the base must be at least 1 foot.
Write and graph a system that represents the situation.
Give one example of a height and side length that the
obstacle course can use.
