Answer:
Luis's school is 7.5 miles from his home.
Step-by-step explanation:
7.5 miles
15 miles per hour
0.5 hours to get home
0.5 x 2=1
So, 15 divided by 2= 7.5
Luis's school is 7.5 miles from his home
That's again the derivative at 2, so the answer is A. 4. Hard way:
f(x)=x²
f(2)=4
f(2+h) = (2+h)² = 4 + 4h + h²
f(2+h) - f(2) = 4h + h²
(f(2+h)-f(2))/h = 4 + h
Limit is 4.
