Amelia is planning the trajectory of her next flight using the altitude and distance from Paris, France. She has determined her function to be f(x) = -4x + 102.

Based on the situation above, describe any necessary restrictions to the domain and range. Provide justification for the restrictions.

Question

Amelia is planning the trajectory of her next flight using the altitude and distance from Paris, France. She has determined her function to be f(x) = -4x + 102.

Based on the situation above, describe any necessary restrictions to the domain and range. Provide justification for the restrictions.

primeralph · Answer

Both have to be greater than zero, otherwise, she'll be going backward and/or underground.

Is that the only justification? @primeralph

primeralph · Answer

There are other restrictions. Think about how the function relates to real life constraints.

gavin39 · Answer

Honestly im just horrible at algebra 2 so have no idea

primeralph · Answer

That's an intuitive question, not algebraic.

primeralph · Answer

Just say the range cannot be negative. Find x that makes f(x) = 0.

ok cool thank you!!!
