A backpack is on sale for 25% off. After the discount is taken, a 7% sales tax is applied. If the original price of the backpack is p, which equation represents the final cost, c, in dollars, of the backpack? A. c = p(0.25) B. c =p(1.07) C. c = p(0.25)(0.07) D. c = p(0.75)(0.07) E. c = p(0.75)(1.07)​

After the discount is taken, a 7% sales tax is applied. If the ... If The Original Price Of The Backpack Is P, Which Equation Represents The Final Cost, C, In Dollars, ...

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
