Answer:
False
Step-by-step explanation:
This is false. We can disprove this by plugging in the number into the function f(x) = lnx
f(0) = ln0
Since
,
This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.
Answer:

Step-by-step explanation:
Given

Find an equation perpendicular to the given function if it passes through (-3,9)
First, we need to determine the slope of: 
The slope intercept of an equation is in form;

<em>Where m represent the slope</em>
Comparing
to
;
We'll have that

Going from there; we need to calculate the slope of the parallel line
The condition for parallel line is;

Substitute 

Divide both sides by -2


The point slope form of a line is;

Where
and 
becomes

Open the inner bracket

<em>Hence, the point slope form of the perpendicular line is: </em>

Answer:
2x^3 - 6x^2 - 4x + 12.
Step-by-step explanation:
(p*q) (x) = (2x^2 - 4)(x - 3)
= 2x^3 - 6x^2 - 4x + 12.
Answer:
It is an exponential function
Step-by-step explanation:
We have the following function:
f (x) = 3/8 (4) ^ x
The function is of the form:
f (x) = A (b) ^ x
Where,
A: initial amount
b: growth factor (b> 1)
x: time variable.
Answer:
f (x) = 3/8 (4) ^ x
It is an exponential function of the form:
f (x) = A (b) ^ x
