Match the expression to the correct property that is shown.
Harrizon [31]

Answer:

This is a help site, so I'll explain each property and see if you can match them yourself.

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.

Commutative Property of Addition - same as the associative property but with 2 numbers.

Identity Property of Multiplication - Any number multiplied by one is itself

Multiplicative Property of Zero: x * 0 = 0

Associative Property of Multiplication - Same as that of addition, yet with multiplication.

Distributive Property: Factoring Out.

EX: (12 x 15) = 3(4 x 5)

Find average rate of change f(x)=-4x^(2)-3x-4 ; [-1,3]
NeTakaya

The rate of change of the given function at [-1,3] is 5

Further explanation:

Given function is:

f(x) = 4x^2-3x-4

And the interval is:

[-1,3]

In order to find the rate of chnage of function the given function's value is calculated at both points and divided by their difference

The formula is:

Rate\ of\ change= \frac{f(x_2)-f(x_1)}{x_2-x_1}

Here,

x_1 = -1

x_2 = 3

So,

f(-1) = 4(-1)^2-3(-1)-4\\=4(1) +3-4\\=4-1\\=3\\f(3) = 4(3)^2-3(3)-4\\= 4(9)-9-4\\=36-13\\=23

Putting the values in the rate of change formula:

Rate\ of\ change= \frac{23-3}{3-(-1)}\\= \frac{23-3}{3+1}\\=\frac{20}{4} \\=5

The rate of change of the given function at [-1,3] is 5
