Answer:
The average rate of change in that interval is 1.99
Step-by-step explanation:
Here we have that the difference quotient for g(x) is:
Remember that for a general function f(x), the difference quotient is:
So if we look at the difference quotient for g(x), we can conclude that:
Also remember that the average rate of change in an interval (a, b) is just:
So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:
The average rate of change in that interval is 1.99
7(2x - 4) + 2(3x + 1) Distribute/multiply 7 into (2x - 4), and multiply 2 into (3x + 1)
14x - 28 + 6x + 2 Combine like terms
20x - 26
Your answer is B
x = 7
y = 2
Plug in the numbers into the variables
4(4) - 2 + 4
16 + 2
18
Your answer is D
