Jack was so frustrated with his slow laptop that he threw it out of his second story window. the height, h, of the laptop at time t seconds can be given by the equation h(t)= -16t^2 + 28t + 17. assuming the laptop hits the ground below, find the domain of the function.

The domain of the function is the interval [0,2.23]

see the explanation

Step-by-step explanation:

Let

t ----> the time in seconds

h(t) ----> the height of the laptop in units

we have

we know that

When the laptop hits the ground, the value of h(t) is equal to zero

so

For h(t)=0

Solve the quadratic equation

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

 ---> is not a solution

therefore

The domain of the function is the interval [0,2.23]

All real numbers greater than or equal to 0 seconds and less than or equal to 2.23 seconds

i dont know
