Arthur has decided to start saving for a new computer. his money is currently in a piggy bank at home, modeled by the function s(x) = 85. he was told that he could do the laundry for the house and his allowance would be a(x) = 10(x − 1), where x is measured in weeks. explain to arthur how he can create a function that combines the two, and describe any simplification that can be done.

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

At the beginning of the day, stock xyz opened at $6.12. at the end of the day, it closed at $6.88. what is the rate of change of stock xyz? a. 1.17% b. 11.0% c. 12.4% d. 81.5%

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
