Answer:
12
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is

Here [ a, b ] = [ 2, 4 ]
f(b) = f)4) = 32 ← from table
f(a) = f(2) = 8 ← from table
Then average rate of change is
=
= 12
Answer:
Factor the numerator and denominator and cancel the common facotors which would give you 0.07843137
The answer is the 5th one

Answer: 13
Step-by-step explanation:
If you remember the quadratic equation formula;

You can easily extract what is under the root to find the discriminant.

a = 3
b = 7
c = 3
