A student is deriving the quadratic formula. Her first two steps are shown. Step 1: –c = ax2 + bx

Step 2:

Which best explains or justifies Step 2?

division property of equality
factoring the binomial
completing the square
subtraction property of equality

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

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.
