ALGEBRA2AlgebraQuestion 1If f(x) decreases with the increase in x, then it must increase as x gets smaller. Therefore, F(−2)would be larger as compared to F(2).Question 2Average rate of change¿Change∈YChange∈X=4.9−2.96.1−2.2=23.9=0.513Question 3∆f(x)∆x=0 at the intervals: 2.2≤x≤5.2 and 5.2≤x≤6.9Question 4Average rate of change¿Change∈YChange∈X=4.9−2.96.1−2.2=23.9=0.513Question 5The average rates of change of f and g between x=2.2∧x=6.1 are equal.Question 6Part aThe rate of change of f is negative
