What is the average rate of change for this quadratic function for the interval
from x = 1 to x = 3?
-5
5
- 10

Expand (x−1)(x−3) ( x - 1 ) ( x - 3 ) using the FOIL Method

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
