The graph of the function f (x) is shown below. when f(x)=0,x=?

From the graph of the function f(x) we have:

        When f(x)=0  ,   x= -1.8

By looking at the graph we observe that the graph first increases in the interval (-∞,-1.2) and then it decreases in the interval (-1.2,0.6) and then again it increases in the interval (0.6,∞).

Hence, the graph of the function is neither strictly increasing nor strictly decreasing in the whole of the real line.

Also, when x=0 the value of the function is: f(x)=5

( Since, the graph passes through the point (0,5) )

Also, when f(x)=0

then x= -1.8

( Since, the graph of the function passes through the point (-1.8,0) )

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the  

service

−−−−−−  

so technically the answer is

however, the intention of the question provider may have been that your answer is to be

(
