As you read about polynomial functions, you can use the words from the table to rewrite "symbol sentences in words. The word sentence that you
write can help you understand the symbol sentence. Here is an example.
Rewrite each symbol sentence as a word sentence.
positive infinity
negative infinity
As x, f(x) -
symbol sentence
1. As x 0, f(x) +0.
Ao x approaches positive infinity
the value of fat x approaches
negative infinity
2. f(-x) = f(x)
3. f(-x) = f(x1) and f(-x) = -f(x2)
Rewrite each word sentence as a symbol sentence.
4. As x approaches negative infinity, the value off at x approaches zero.
5. The opposite of the value of fat x is not the same as the value of fat x.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

answer:   c ?

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
