Answer:
A.
As x decreases in value, f(x) decreases in value.
As x increases in value, f(x) increases in value
Step-by-step explanation:
From the graph provided;
when x=0, y= 3
when x = 2, y is approximately equal to 4
when x = 5, y = 5
when x = 9, y = 6
Clearly, as x values increase from 0 , the y-values are also increasing from 3.
Therefore, it is true to say that;
As x decreases in value, f(x) decreases in value.
As x increases in value, f(x) increases in value

Answer:
3^x-8=8 then x=log_3(16)
3^(x-8)=8 then log_3(8)+8
Step-by-step explanation:
So if it is 3^x-8=8
then 3^x=16
and then convert to logarithmic form you write it as log_3(16)=x
_3 means the subscript (the base) is 3
So if it is 3^(x-8)=8
then the log form is log_3(8)=x-8
add 8 on both sides log_3(8)+8=x
.48x =36 x=36/.48 x=75 So the total distance to kirk's grandmother's house was 75 miles
