Natural Gas costs about $5 per 1000 cubic feet I have only 196.512 cubic feet. What is the total cost?

0.98256

Step-by-step explanation:

196.512 /1000

x5

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
