Question

The equation h(t) = -4.9t^2 + 40t gives the height in meters at t seconds of a projectile shot vertically into the air.

d.) What is a realistic domain for t??

Answer 1

domain is all x values . in this case all t values. this is a quadratic function so t can take values from -infinity to +infinity. But here t is time there is no negative time so the domain is from 0 to + infinity

Answer 2

K thanks! :) I appreciate it!
