Answer:
3/4
Step-by-step explanation:
f(0) - f(3) / 0 - 3
f(0) = -4
f(3) = 9/4 - 16/4 = -7/4
f(0) - f(3) = [-4 - (-7/4)]
f(0) - f(3) = [-16/4 + 7/4]
f(0) - f(3) = -9/4
-9/4 ÷ -3 = -9/4 · -1/3 = 3/4
Step 4-5 is where Andrew made an error. Since 9.8 is positive, -11.8 + 9.8 = -2. He subtracted 9.8 from 11.8 instead of adding it.
