Dr. Dre is the founder and CEO of Aftermath Entertainment and Beats Electronics. On the release day, Dr. Dre sold 300 Beats and averaged 30 Beats per day after that. Which equation models the number of Beats, b, Dr. Dre sold after d days?

d=30+300b

d=300+30b

b=30+300d

b=300+30d

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

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
