A cable TV company charges a flat fee of $25 for basic cable service, plus extra for each movie a customer watches. Here is some of the pricing
information:
Movies watched
0
1
2
3
Cable TV bill ($) 25 29 33 37
According to this information, how many movies can a customer watch and
still keep his or her bill under $70?

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
