A. About 1/2 kg

             I swear its right I just took the quiz on khan academy

Step-by-step explanation:

Hey there!

We know that formula for the difference quotient is [ ]

We need to find f(x + h), so use (x + h) instead of x.

f(x + h) → -(x + h)² because we are given [ -x² ]

-3(h + x) + 1 because we are given [ -3x + 1 ]

Put what we found into the formula and simplify.

Therefore, the difference quotient for the given function is [ -h - 2x - 3 ]

Best of Luck!
