Y=5/2x-19 and 5x+2y=-8 a perpendicular, parallel or intersecting lines?

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.

Pls never taught i’m really confused and i rlly need

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x
