Answer:
The average rate of change is 8
Step-by-step explanation:
Mathematically, we have the average rate of change over a given interval as;
f(b) - f(a)/b-a
Where the interval is [a,b]
With respect to this question, a = 3 and b = 5
f(a) = f(3) = 3^2 - 4 = 9-4 = 5
f(b) = f(5) = 5^2 - 4 = 25-4 = 21
Thus, the average rate of change over the intervals will be;
(21-5)/(5-3) = 16/2 = 8
Answer:
-4 square units
Step-by-step explanation:
a = l × b
x2 - 3x - 28 = (x +4)(×)
x2 - 3x - 28 = x2 + 4x
-3x - 28 - 4x = 0
-7x - 28 = 0
-7x = 28
x = -4
