Question

The function N(t) = 80.375t2 + 1,505 represents Nevin’s elevation in feet over time in hours. c. Find the y-intercept for Nevin’s and Bruce’s functions. Do both functions have the same y-intercept? The y-intercept is 79.65

Answer 1

We find the y-intercept by substituting t=0:
$N(0)=80.375(0)^2 + 1,505\\=1,505$:
The y-intercept is then the point (0,1.505).
