Use this information to answer questions 13-16: On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet,
of the balloon x hours after starting its ascent from the hill, can be modeled by the function
h(x) = -16x+ 64x + 80. use desmos calculator
There is a positive and negative x intercept for this function. What is the positive x-intercept? Explain what this
X-intercept represents in the given situation.
