Question 1098318
A grasshopper jumps off of a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modelled by the function shown.

-t^2+4/3t+1/4
 
After how many seconds will the grasshopper land on the ground?
\\\\\\\\\\\\\\\\\\\
That's not a function.
If you mean
h(t) = -t^2+4/3t+1/4
That's a function, but it's not clear.
---
Is it {{{h(t) = -t^2+4/3t+1/4}}} ?
Or {{{h(t) = -t^2+4/(3t+1/4)}}} ?
Or something else?
