Answer:
Linear non-linear
x<2 , x>5 2<x<5
Step-by-step explanation:
When a function is linear then the graph is a straight line
When the function is not linear then the graph is like a curve
From x = - infinity to 2 the graph is a straight line
So from - infinity to 2, the function is linear, that is x<2 function is linear
from 2 to 5 the graph is like a curve , so it is not linear
2<x<5 , the function is not linear
From x = 5 to infinity the graph is a straight line
So from 5 to infinity, the function is linear, that is x>5 function is linear
Answer:
[H^+] = Antilog[-6]
Step-by-step explanation:
Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.
pH=−log[logH^+]
-pH = log[H^+]
[H^+] = Antilog[-pH]
Since pH =6
The equation is;
[H^+] = Antilog[-6]
Answer:
(x-1) is factor of our function.
Step-by-step explanation:
We are given a function
and we are asked to find the correct factor from the given options.
Let us factor out our polynomial.



Therefore, (x-1) is correct choice for factor of our polynomial.
You circle the area where it states the ending of the declined point. In this case, circle the 5 hours.
There's no if about it,

has a zero

so

is a factor. That's the special case of the Remainder Theorem; since

we'll get a remainder of zero when we divide

by

At this point we can just divide or we can try more little numbers in the function. It doesn't take too long to discover

too, so

is a factor too by the remainder theorem. I can find the third zero as well; but let's say that's out of range for most folks.
So far we have

where

is the zero we haven't guessed yet. Again we could divide

by

but just looking at the constant term we must have

so

We check

We usually talk about the zeros of a function and the roots of an equation; here we have a function

whose zeros are
