The initial payment per month being 30 and each movie being 2.50 means that if the total payment is 45 then you pay for 6 movies per month, 30x+6(2.5x)
for the value of
we have the function f(x) = 1/(x-2) or
as undefined or not defined .
<u>Step-by-step explanation:</u>
<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity .
Here we have , Function f(x) = 1/(x-2) or
. We need to find a value of for which this is not defined . Let's find out:
We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or 
⇒ 
⇒ 
⇒ 
Therefore, for the value of
we have the function f(x) = 1/(x-2) or
as undefined or not defined .
Do the variable first (x^2 +4x) then do y+y-8
X to the second =4×3
x=√(12)
