Step-by-step explanation:

Complete Question:

Consider the function represented by the table

the ordered pair given in the bottom row can be written using function notation as,

a) f(9)=5

b) f(5)=9

c) f(5,9)=14

d) f(9,5)=14

Solution:

"x" is the input and "f(x)" is the output. We always write a function in the form:

f(m) = A

Where m is the input (x value), and

A is the output (y value or f(x) value)

Now, looking at the table, we see that x value is "9" and f(x) is 5

Thus, we can write:

f(9) = 5

Correct answer is A

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
