What is the vertex of the graph of y = –x^2

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

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.

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers
