Answer:
The average rate of change in section 2 is 25 times larger than the average rate of change in section 1.
Step-by-step explanation:
Recall that the average rate of change of a function in an interval [a,b] (section of the number line) is defined as:
Rate of change =
Therefore:
1) First interval: evaluating the rate of change from x=0, to x=1 (interval [0, 1]) it becomes
Rate of change =
2) Second interval: we now evaluate the rate of change from x=2 to x=3 (interval [2, 3]), so it becomes
Therefore, the rate of change in the second interval is much larger than the rate of change in the first one. The second rate of change is in fact 100/4 = 25 times larger than the first rate of change. this is due to the fact that the function is an exponential function and not a linear function (where the rate of change is constant)
The Discriminant = b²-4ac
1.
a=2
b= 5
c=-3
The Discriminant is 49
When a, b and c are real numbers, a ≠ 0 and discriminant is positive and perfect square, then the roots α and β of the quadratic equation ax2 + bx + c = 0 are real, rational unequal.
2.
a=-1
b=1
c=1
The Discriminant is 5
When a, b and c are real numbers, a ≠ 0 and discriminant is positive but not a perfect square then the roots of the quadratic equation ax2 + bx + c = 0 are real, irrational and unequal.
3.
a=1
b=6
c=11
The Discriminant is-8
then the roots α and β of the quadratic equation ax2 + bx + c = 0 are unequal and imaginary.
4.
a=9
b=-54
c=81
The Discriminant is 0
the roots α and β of the quadratic equation ax2 + bx + c = 0 are real and equal.
For this case we have the following expression:
We apply distributive property:
We rewrite in equivalent form:
