Which law would you use to simplify the expression....​
sammy [17]

Answer:

power of a power

Step-by-step explanation:

the power of a power law says that, "if a base raised to a power is being raised to another power, the exponents are multiplied and the base remains the same."

for example, for this problem, you would do:

(x^4)^9\\= x^4^*^9\\= x^3^6

Consider the function f(x) = 4 - 2x ^ 2 on the interval \ -6,6] Find the average or mean slope of the function on this interval
Daniel [21]

f(x) = 4 -2x^2

First we need to find f(6)

f(6) = 4 - 2( 6) ^2 = 4 - 2(36) = 4 - 72 = -68

Then we need to find

f(-6) = 4 - 2( -6) ^2 = 4 -2( 36) = 4 - 72 = -68

Now we find the average or mean slope

The mean slope is zero

Now f'(c) must equal 0

The derivative is -4x and evaluated at c

-4c

This must be equal to 0

-4c =0

Solving for c

c=0
