Answer:
A. f(x)=9x+4
Step-by-step explanation:
Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;
if x=5,then f(5)=9*5+4=45+4=49
<span>
f(x) = 2(3x)
Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses.

Answer:
2.835
3.330
Step-by-step explanation:
Let the linear approximation be L(x) at a = 0. This is given by
is the derivative of . To find this, we use the form
If , then
By doing this and applying chain rule for the power (which is a function of x), we have
Then
Also
Hence
For , and
Using this in ,
For , and
Using this in ,
